How one can say about a device (e.g: a light holder
contains 20 or 30 L.E.Ds which glows when power supply is
off, from which source they are getting the supply.....
battery or capacitor) without removing and opening up its
case ?

What are some good estimates for heat transfer coefficients
for coils in tanks?
The magnitude of electrostatic force between two identical
positive ions that are separated by a distance of 5.0 x 10–
10 m is 3.7 x 10–9 N. (a) What is the charge of each
ion? (b) How many electrons are “missing” from each ion?
