Question 192 of 311

In an electrical circuit, a battery is connected to pass 20C20C of charge through it in a certain given time. The potential difference between two plates of the battery is maintained at 15V15V. The workdone by the battery is _______ JJ

Show answer and solution

Answer: 300

Work done by battery =Q(ΔV)=Q\left(\Delta V\right)
⇒20×15=300J\Rightarrow 20\times 15=300J
=300=300
