How much work is done in moving a charge of $2 \ C$ from a point at $118 \ V$ to a point at $128 \ V$ (in $J$)?

Study the $V - I$ graph for a resistor as shown in the figure and prepare a table showing the values of $I$ (in amperes) corresponding to four different values of $V$ (in volts). Find the value of current $I$ (amperes) for $V=10$ volts. How can we determine the resistance of the resistor from this graph?

Derive the relation $R = R_{1} + R_{2} + R_{3}$ when three resistors $R_{1}, R_{2}$ and $R_{3}$ are connected in series in an electric circuit.

An electric lamp is marked $100 \, W, 220 \, V$. It is used for $5$ hours daily. Calculate: $(i)$ its resistance while glowing. $(ii)$ energy consumed in $kWh$ per day.

State $Ohm's$ law. Calculate the resistance of a conductor,if the current flowing through it is $0.2 \, A$ when the applied potential difference is $0.8 \, V$.

The amount of $2 \ A$ electric current is passed for $1 \ minute$ through a conducting wire. How much total electric charge will pass through this wire (in $C$)?
