Question 15

How much work is done in moving a charge of 4 C across two points having a potential difference of 12 V?

Solution

We know that,

$$W = q \times V$$

Where q is charge , W is the work done and V is the potential difference .

As given work is done in moving a charge of 4 coulomb across two points having a potential difference of 12 volt.

q = 4 Coulomb

V = 12 Volt

Put all the values in the formula

$$W = 4\times12$$

W = 48 J

Option A is correct.
