Electrical Power & Heating Effect

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.

Numerical answer type. Work it out, then open the answer.

Show answer and solution

Answer: 300

Work done by battery $W = qV$ .
$W = 20 \times 15 = 300\ \text{J}$ .
