If $1\, ampere$ electric current passes through a conductor, how many electrons will pass per second?
Of the two bulbs in a house, one glows brighter than the other. Which of the two has a larger resistance ?
$1\;kWh =\ldots\ldots$ $joule$
A series circuit has only one conducting path for the electrons that move through it; a paralle circuit has multiple conducting paths.
There is a frill of $20$ bulbs connected in series in a room. One bulb gets fused. The remaining $19$ are again joined in series and connected to the same supply. Will the light increase or decrease in the room ?
