If the charge on an electron be $1.6 \times 10^{-19} C$, find the approximate number of electrons in $1 C$
The unit of electric potential difference is $.....$
A current of $1\, A$ is drawn by a filament of an electric bulb. Number of electrons passing through a cross section of the filament in $16$ seconds would be roughly
What will be the equivalent resistance between points $A$ and $B$ of the following electric circuit?
A wire connected to a bulb does not glow, whereas the filament of the bulb glows when the same current is passed through them. Why ?
