Quora answers need not be 100% correct answers Compiledand posted by R. Gopala krishnan, on 15-10-2023 Q1 What is the average lifespan of a switch mode power supply? A1 Mohak Malviya, B.Tech from Shri Govindram Seksaria Institute ofTechnology and Science (SGSITS) (Expected 2025)1h A switch mode power supply's (SMPS) design, quality,usage circumstances, and load can all have a significant impact on how long itlasts. For instance, some powersupplies like the TDK RWS50 are quoted to have a Mean Time Between Failures(MTBF) of about 4,170,949 hours, which is approximately 500 years. However, this doesn’t mean the power supply will last that long inpractical use. Components such as mechanical fans and electrolyticcapacitors within the power supply have much shorter lifespans. For example,mechanical fans usually have at most 40,000 hours of life, and the bestelectrolytic capacitors are rated at 100,000 hours at 60°C. It’s also important to note that the lifespan of these components candouble with every 10°C drop in operating temperature.Therefore, keeping the power supply cool can significantly extend its lifespan. However, these aretheoretical values and actual lifespans can be much shorter due to variousfactors such as power surges, dust accumulation, and component aging. For a more preciseestimate for a specific model or brand, you may want to refer to themanufacturer’s specifications or contact them directly. Please note that this information is accurate up tothe year 2023 October month. Q2 Why Airplanes Have Ashtrays, Even Though Smoking is Banned? A2 Vishnu Ravi,21h In an era where smoking has been strictly prohibitedaboard airplanes, you might be wondering why ashtrays still find a place inairplane bathrooms. Well, there's a compellingreason behind it. The Federal Aviation Administration(FAA) mandates that all aircraft lavatories must be equipped with ashtrays,irrespective of smoking being allowed anywhere else on the plane. Why, you ask? It's a matter of safety and foresight. If, against all regulations,someone were to attempt lighting up in the lavatory, they need a secure spot toextinguish their cigarette. Without these ashtrays, thesituation could turn hazardous. Imagine a scenario where panickedpassengers dispose of their lit cigarette in the trash bin, potentially causinga fire when it comes into contact with the waste paper already inside. These ashtrays are intelligently designed to beself-contained and easily removable, placedconspicuously on or near the entry side of each lavatory door. And, here's aninteresting fact: if any ashtray is found to be malfunctioning, airlines areobligated to replace it within three days. It's a small yet crucial detail that ensures everyone'ssafety in an unlikely event. Q3 What is the purpose of a current transformer (CT) in a meter? A3 Kev Go, Training Electricians (2012–present)Sep 30 Large electrical installationsdraw hundreds or thousands of amps from the supply grid. and sometimes at veryhigh voltages. How can we measure that current with common meters? WE use a current transformer. This steps the current down from hundreds or thousandsof amps to perhaps5 or 20 Amps so we canmeasure that with ordinary common current or power instruments….

Q5 How familiar are Zambians with Chinese culture, traditions, andlanguage? A5 Junya Gao, Wed Fluid Taichi movements, dynamic Shaolin Quantechniques, and forceful kicks --- one could hardly imagine traditional ChineseKung Fu executed so proficiently by a group of African children. Their training ground is not in China but at a Shaolin Temple in Zambia. The Temple on the outskirts of Zambia's capital is thefirst in Africa. It now serves as a beacon for many Africanskeen to immerse themselves in the art of Kung Fu. Having reported from Africa for over five years, thelocal enthusiasm for Chinese Kung Fu never ceased to amaze me. Timeand again, I was greeted with iconic Kung Fu stances. Legends like Bruce Lee,Jackie Chan, and Jet Li are etched in the local consciousness. This Shaolin Temple not only satiates many Kung Fuenthusiasts but also provides a gateway to Chineseculture and language. What needs to be pointedout is that the Shaolin Temple also offers classes on Chinese culinary arts,something many Chinese, including myself, would be keento experience. On a side note, I hope they consider teaching how to cookNshima, too, my favorite African staple. My tenure in Africa offered me a firsthand look at theburgeoning China-Africa cooperation. While bilateralcooperation has grown exponentially, I've always felt a slight disconnect in mutualunderstanding. I think Zambia is the most familiar name for Chinesepeople when it comes to African countries. For many Chinese people, Zambia issymbolic of the China-Africa bond, primarily due to the Tanzania-Zambia Railwaybuilt by China in the 1970s. However, there seems tobe a knowledge gap concerning daily life, languages, cultural nuances, etc. Therefore, I think the strengthening of culturalexchanges and people-to-people interactions between China and Africa iscrucial. It brings me enormous comfort and joy when the headmaster of the ShaolinTemple in Zambia states that their mission encompasses not just martial artsbut also deepening mutual appreciation for Chinese and African cultures andenhancing China-Africa friendship. With this trajectory, envisioning Kung Fumovies featuring African protagonists seems a near-future reality. Such developments furtheraccentuate the strengthened ties between China and Zambia. In recent years, China and Zambia have cooperated in a wide range of fieldswithin the framework of the "Belt and Road" andthe Forum on China-Africa Cooperation or FOCAC. Regarding education, the Chinese language has been officiallyincorporated into Zambia's junior and senior secondaryschool curriculum. It holds promise not only for Zambians who aspire tostudy or work in China but also for those eyeinglocal job opportunities. Considering that around 80,000 Chinese individualswork in Zambia, this linguistic addition is poised to open doors to numerous professions. I would not be surprisedto be regaled with stories in fluent Chinese the next time I visit the Devil'sPool. During President Hakainde Hichilema's recent visit toChina, the two sides elevated relations to a Comprehensive Strategic CooperativePartnership. This recognition is atestament to friendly interactions over the past 60 years. It will also furtherdeepen the bond in the years to come. It's the time of the year when jacaranda trees in Zambiaburst into bloom, painting towns in mesmerizing shades ofpurple and blue. I'm engulfed in nostalgia. And I'm confident that China-Zambia ties will continue toflourish year after year like the beautiful Jacaranda. -- You received this message because you are subscribed to the Google Groups "Thatha_Patty" group.
