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.

Step-by-Step Verified Solution

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.

∴ W = qV = 20 × 15 = 300 J
