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 the circuit shown below, calculate

$(a)$ total resistance in arm $CE,$

$(b)$ total current drawn from the battery, and

$(c)$ current in each arm, i.e., $A B$ and $C E$ of the circuit.

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

What is meant by "electrical resistance" of a conductor ? State how resistance of a conductor is affected when $(i)$ a low current passes through it for a short duration; $(ii)$ a heavy current passes through it for about $30$ seconds.

A wire of resistance $5 \,ohm$ is bent in the form of a closed circle. What is the resistance between two points at the ends of any diameter of the circle?

You are given three equal resistors. The number of resistances which can be obtained by joining them in series and in parallel grouping is
