$A$ current of $0.5\, A$ is drawn by a filament of an electric bulb for $10$ minutes. Find the amount of electric charge that flows through the circuit. (in $C$)

On which of the following factors does the resistance of a conductor depend?

What is the process of depositing a layer of gold on silver called?

The equivalent resistance between points $A$ and $B$ in the following electric circuit is:

$(a)$ Define potential difference between two points in a conductor.
$(b)$ Name the instrument used to measure the potential difference in a circuit. How is it connected?
$(c)$ $A$ current of $2 \, A$ passes through a circuit for $1$ minute. If the potential difference between the terminals of the circuit is $3 \, V$, what is the work done in transferring the charges?

If the diameter of a conducting wire is doubled,how many times does its resistance become?
