Q1 Why is the fuse in the neutral wire? A1 Steve Jones Studied atImperial College London Updated September 13 That would be because it was fitted by anincompetent electrician. Fuses should never be fitted to the neutral wire. That’s because it provide no protection for live/line to ground/earthfaults and also, if there is an over-current live to neutral fault, and thefuse blows, it still leaves the circuit energized. Q2 How do I decrease the temperature in an AC? A2 Bruce Skovmand, formerJourneyman Electrician & Electrical Theory Teacher (1957-2017)Answered June20, 2020 Since degrees is set up so, the lower the number, the colder it gets,when you say “ decrease the temperature “ you mean to set it at a lower number…The other way to look at it is, if it’s getting too cold, warm it up byincreasing the number to a higher temperature. Q3 How can I take care of my laptop battery (Li-ion) while Ihave to work on the laptop at the desk most of the time every day? Should I useplugged in all the time or any other way? A3 Ashok Pandey Managerat Cyber Media India (company) (2014–present)August 6 The best way to care for yourlaptop's battery is to keep your laptop plugged while using it. If you don't, then it will run on battery, whichwill actually reduce its battery life. That's because all batteries have a certain numberof charge and discharge cycles. The more you use it on battery, the morecycles are used up, which ends up reducing battery life. If you're looking for a laptopwith long battery life, then check out some of the HP business notebooks. They not only offer long battery life, but have a Fastcharge technology that can recharge the battery upto 50% in just 30 minutes. Q4 What purpose does silver have in household products likeantiperspirants and water filters? A4 Anonymous Answered 26mago Inhibiting the growth of bacteria Silver ions have wonderfulantibacterial properties and so are useful additions to products where growth is likely. Antiperspirants, in particular,include a smattering of silver ions designed for a spot of minor odourabsorption in addition to preventing a bacterial breakout. Silver in water filters helps tocleanse the water and is a common addition to drinking water supplies and pools(where it can be used as a safer alternative to chlorine). Q5 Why was gold one of the first metals to be mined andworked by the ancients? A5 John Bartram· Studiedhistory and practised archaeology worldwide for 50+ years. Fri Where gold was found, it was found easily, sitting, glinting, in streams. It could then be beaten with arock into shapes and even into sheets; it required no metallurgy, or kiln. And to top it all, itnever corrodes and so keeps its lustre forever. Q6 Why is it dangerous to plug high power capacityappliances into power strips or extension cords? A6 Lewis Edge, B.S.Electrical Engineering, Georgia Institute of Technology (1964)Answered 15h ago In North America most standard electrical outlets can safely deliver upto 15 or 20 amperes at 120 AC volts. Many extension cords are designed forlight electrical loads, such as table lamps or floor lamps. If such an extension cord isused for a high power capacity appliance it can be overheated and cause a fire. A solid power strip, designed to deliver a full 20-amperes can be usedsafely. However, any time an additional plug-in connection is made between ahigh power capacity appliance and the outlet, there is a possibility that therewill be a high-resistance connection that can overheat. That’s why suchconnections are discouraged. My note-If you are insertingthe extension box to 5 ampsplug point, the total load in amps should not exceed 5 amps .Wattage/Voltage(230)= amps. Q7 What is the main difference between a lithium battery anda lithium-ion battery? A7 3 Answers AnonymousAnswered 58m ago A lithium battery is non-rechargeable,whereas a lithium-ion battery is rechargeable In general, lithium batteries are non-rechargeable (primary batteries).The lithium metal serves as the anode, whereas another material (for example,manganese dioxide and iron disulfide) serves as the cathode. On the other hand, lithium-ionbatteries are rechargeable (secondary batteries). The first lithium-ionbattery prototype was built by Japanese chemist Akira Yoshino in 1985. Both lithium and lithium-ion batteries operate through redox (reduction-oxidation)chemical reactions. Lithium batteries are bändin-rechargeable batteries that use lithiuminstead of zinc as anode. The typically are button shaped about coin sized andhave 3 V voltage. There also are 1.8 V ones in normal AA and AAA sizes. Thedecan in most devices be used instead of alkaline batteries. Such lithium batteries workmuch longer on heavy load and have very long shelf-life - up to 20 years. Lithium-ion batteries arerechargeable batteries that have 3.7 V nominal voltage. They nowadays typicallyare built in devices like phones, tablets, wireless headphones etc. Some devices like cameras use user changeable Li-ion batteries that arespecifically designed to the devices. Users generally do not buy genericstandard size Li-ion batteries for devices like they do with AA and AAAbatteries. Q8 What is the significance of the color black in Indianculture? A8 AnbazhaganAmbroseM.Phil. in Literature & Linguistics, Jawaharlal Nehru University(Graduated 2000)September 15 I do not know about “Indian” culture, but I do know a bit about Tamilculture. In North Tamilnadu significanceof black varies. If yourfamily is entitled to worship “katteri” black is not only allowed, it is alsoencouraged. But if you do not, woe betide anyone who dares to wear black. I am banned from wearinganything black in my mother’s presence. My mother will reject any cloth that has even a tiniest black thread, leave alonewhole black borders and stuff. Even my father, a hard core DK/DMK person, decided discretion is betterpart of valor and never wore black. At least he did not come home wearing black. Q10 What is the reason that any pooja lamp (Deepam) should belit by 12 noon or after 4PM? What is the logic, history, history behind notlighting the first deepam for poaja after 12 noon? A10 Ramadevi Gidugu FormerSelf Employed, Full Time Mother. Sun I was told by learnt pandits, a day is divided and ruled by Deva, Manava,rakshasa and pitrudevatas. Means god eliments, human eliments and demons or evil eliments anddeparted souls awaiting birth. >From four to 6 deva kalam. 6 to 11 manava kalam. Then onwards up to 4it's >pitrudevata sancharana time.( Departed souls) From then onwards asurastime.( >Evil eliments) In this uttamam( the best )is early morning four to 6. It's not easy forevery one. So, Manava time( human eliments) is followed by many for nitya puja.Lighting of lamp. That is up to 11 am. Later, only death or annual ceremonies for departed souls are performedtill 4 in the evening. Later on asuras( evil spirits) time starts. To avoid them we light lampas we believe evil spirits won't come when there is divine positive energy, light. Generally in sandhya samayam ie evening between 5.30to 6.30 lamp is lit. But technically from four we can light the lamp. But, that will be broad day light. So, generallywe light lamp from five onwards. ‘Deepam andhakara vinasanam'timira samharam'. Means lamp is lit to drive away darkness. If you can observe, to follow this schedule one needs a lot of disciplinein life. All pujas, rituals, traditions main intention is, to have, to teachsome discipline in life. Again some gods who have the control and who deals only with demons arethere. Like, Maha kali, lord shiva, and a few. For them night puja is allowed.Any time of the day puja is allowed. Many of them for occult practices also. Any puja once started in Deva and manava time, can continue to any lengthof time irrespective of the time of the day. Because that is continuation ofthe process already strated. Like havan, homam, abhishekam. It's really a big, vast subject. I tried to explain it in brief.Itdoesn't mean you can't do whenever you want to do puja, you can. Only thing isthe expected results may not come. Early mornings, mind will be in fresh mood. Stomach is empty. After bathonly puja is generally performed. So, mind and body both are clean and in receiving mode. Any positiveenergy can easily penetrate body. It activates and helps your brains and bodyto perform well. Same way, once you finish your day activities, you freshen up yourselfand light evening lamp. A good time to receive positive energy to relax yourbody. Helps your body and brains to relax. Helps you perform your dutiestowards your family. I don't have scientific backingfor this information because these pandits who told me are scholars not sciencegraduates. Moreover I didn't find anything objectionable or degrading in what theysaid. So, I never questioned them to prove anything. I followed their advice and benefitted from it.Inever have a reason to prove them wrong. Q11 Despite a lot of Indians in information technology, why isthere no competition to companies like Facebook, Amazon, and Google? A11 KanthaswamyBalasubramaniam Lawyer Fri Thats because the West is muchmore prosperous thanIndia and development and demand always originates earlier in prosperouscountries than in poorer countries. Take the PCs and Windows. US had PCs since 1988–89 in various housesbeginning with Commodore 64 and slowly evolving to Windows 98 and later ME. Yet while every kid in US had a PC and every home had a PC by the 2000s. Even in 2003- How many homes inIndia had PCs? So we are looking at a 15 yr gap between demand related developmentbetween US and India US had started facebook in 2004–2005 because their students were at thatstage where they had a demand for Social Media. And you had Hi5, Orkut, Myspacealso. In 2004–2005 India, ourinternet was still 80–90% dialup connections and slow as hell, so how could anyone conceive facebook or youtube or twitter.The Demand never existed or was unimaginable Also who developed Facebook? A group of college kids Who developed Microsoft? A College kid Apple? Twitter? Whatsapp? Google? All by Kids in their 20s not byAccenture or IBM or HP or Compaq Lets take our College Kids Middle Class ones need Jobs to pay offEducation loans and get ahead Rich onesjoin Papas business Our Kids don’t have a tenth of the freedom US kids have like SocialFreedom (Nobody cares too much if you drop out), Academic freedom (Drop out andjoin back 2 years later), Job opportunity (McDonalds, KFC, Summer Jobs, StudentJobs at $7.25/Hr Minimum ), Affordable equipment (Laptops easily affordedagainst 50–60K in India) So another big obstacle .This is the Attitude.Invention takes time andfailure rate is high So rather create an app using the most generic freeware and call itToilet cleaner where people will come and clean your toilets and have Varundhawan pose for it, and two years later value it for $2 Billion - thats the Indian way. Alwaysshortcuts Meanwhile those who do develop something extraordinary don’t get anyfunding and move to US or Singapore where better VCs are able to spot thepotential. Then you have Zero Tech related entrepreneurship This means your idea can be copied in 10 minutes without any issues ID came up with Idly or Dosa Batter and tens of thousands of homes didnot need to grind dosa flour. Dosa grinder sales to homes crashed But in 3 years - every local market was flooded with Cottage Dosa Flourand ate 57% into his share So #1 We are 10–15 yrs behind theWest so demand related innovation isnext to impossible #2 Most innovation comes fromCollege Kids who in Indiasimply have no advantages #3 Our Colonial Attitude isFast Profits meaning we hate longwork and patience to develop quality stuff rather creating worthless junk andhyping about it through media and SRK #4 Since most ideas have no tech uniqueness , they are copied in seconds making it risky and notincentivising enough Q12 What is the benefit of moving towards electric vehicles whenwe know that ultimately we'll need to burn fossil fuels like coal to generateelectricity? A12 Bala Senthil Kumar Asrequired Sun Efficiency. The pollution generated even at the most polluting coal burning powerplant to generate the power needed to charge your car or two wheeler is lessthan the pollution you will create running your EV on fossil fuel. It is like the energy efficiency of a community kitchen. If youdistributed the raw materials and each home cooked the same meal forthemselves, with their own energy, it would be much more wasteful. But cookcollectively and although you have the same process, efficiency is much higher. We do not yet have the fullystudied numbers on the impact of recycling degraded batteries, but that apart, it’s pretty finite the amount ofpollution we might create using electric vehicles. The most important aspect of making the choice to move to EVs is that thesource of power is flexible, and evolving. Those of us who want to do this canalso install solar cells, and go off grid - this option is available already. As we evolve all electricity sources that power our lives, the level ofpollution will keep going down, and we’re seeing diverse sources - solar, wind,wave energy, solar thermal, nuclear, and others coming up that won’t damagemuch to create usable electric power. There is still plenty of untapped hydroelectric power too. I’m not sureif the numbers work in all countries to get more out of water flow, but placeslike Nepal most certainly can become big suppliers to a ‘global grid’ of thefuture, which I think is inevitable.
