For those of you who have sighted family members in the household. I have
two emergency battery powered lanterns and a few flashlights. From now on
the batteries will be stored in plastic bags tied to the lanterns and
flashlights. We just checked them since it is starting to snow and yesterday

Dale,
That's a cute idea, first means of doing it that comes to me involves a
so-called bridge rectifier directly off the battery with a single seperate
diode that would feed a voltage to some pin in one direction and not
the other. Only problem with this scheme is the rectifiers cause you to

Gary,
Nope, when an incandescent bulb burns out the fillament that causes it to
glow breaks and thus no current flows.
I can't absolutely say for sure about fluorescent bulbs, it may be that a very
small amount of current flows through the electronic ballasts when
the bulb dies, but I'd guess n
Yes it does.

The older magnetic ballast draw some current before the bulb is put in. I
believe the electronic ballasts also draw a little without the lamp.. Can't
really say about the cf bulb after it burns out.

sounds like an interface between talkingtherm and the service company is

If the therm has a waranty, and they keep the manual of it on your file,
then they will have what they need to hold the waranty on your job.

Does your dehumidifier gather a lot of water?
Ours has a 24 pint container to gather the water

A colleague just read me a brief blerb about a new power device

I don't know about that.
Say, a few elements in the glue under tiles at the top of the basement stairs.
The alarm would sound even during a power failure.
I wonder how much power can be generated?

Dale,
The blerb didn't spec the amount of power available, might not be enough to
sound an audible alarm, although probably enough to send a radio signal
to a main alarm panel which could have batteries. this gizmo would elminate

I beg to differ. Current can not pass through an open circuit. When a
light bulb is burned out its filament is open. Current cannot possibly flow

The light bulb may be inactive, but I believe that the socket into which you
plug it is not.
Therefore, when I have to change a bulb, I always turn the power off at the
mains.

Sounds like they're too cheap to fix the problem so they put in a lower

You're of course correct, there is voltage at the light socket
even when there is nothing in said socket, but there is no current flow
until you, or a less intelligent consumer, sticks something in

It's, as max says so well, the difference between voltage and current.

for the flashlights using C or D batteries you can take the second
battery and just insert it the wrong way and it could be fine . I
also like the idea of storing the batteries in a bag outside the

Jewel. You are quite right to do so. The voltage is there even with no
current flowing. When you touch a live wire it causes current to flow
through you and that's what knocks you on your pretty little butt.
