Question

What is the potential difference between the terminals of a battery if 250 J of work is required to transfer 20 C of charge from one terminal of the battery to the other?

Answer 1

Dear Student,

◆ Answer -

V = 12.5 V

● Explanation -

# Given -

W = 250 J

Q = 20 C

# Solution -

Work required to tranfer charge across PD is calculated by -

W = V × Q

V = W / Q

V = 250 / 20

V = 12.5 V

Therefore, potential difference across terminals of battery is 12.5 V.

Thanks dear. Hope this helps you...
