Question 169: Current Electricity

Question

In an electrical circuit, a battery is connected to pass 20C of charge through it in a certain given time. The potential difference between two plates of the battery is maintained at 15V. The workdone by the battery is __________J.

Accepted Answer

Given, charge passing through circuit, q = 20 C
Potential difference between two plates,
V = 15 V
Let W be the amount of work done by battery.
$$	herefore$$ W = qV = 20 $$	imes$$ 15 = 300 J
