Given:
The lamp draws the current is

The voltage supplied by the generator is

The time for which energy converted is

Step-by-step explanation:
(a)
The power delivered by the generator is given by

Plugging all the values in the above equation, we get

The power delivered by the generator is

(b)
Energy is converted by the electric lamp is given by

Plugging all the values in the above relation, we get

Thus, the electric energy convert by the lamp is
