Question

The potential difference between the two terminals on a battery is 9 volts. How much energy is required to transfer 150 coulombs of charge across the terminals?

a. 0.06J
b. 600J
c. 17J
d. 1350J

Answer 1

Answer: 1350J

Step-by-step explanation:

To solve this, we are going to use the formula for calculating potential difference which is:

Potential difference (V) = Work done (W) / Total charge (C)

Therefore,

9 volts = Work done / 150

Work done = 150 × 9 = 1350J
