A charge of +3.1 × 10-16 coulombs is moved between two points, resulting in a potential difference of +15 volts. What is the magnitude of the work done on that charge?

Explanation:

The work done is the product of charge and potential

Thus work = 3.1 x 10⁻¹⁶ x 15 =  4.65 x 10⁻¹⁵ J

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.
