Question

How much work is done in moving a charge of 3 C across two points  having a potential difference of 9 V.​

Answer 1

Answer:

The potential difference(p.d) between two point in an electric circuit is defined as the amount of work done in moving a unit charge from one point to the other point. Hence, the work done in moving the charge is 45 J

Answer 2

Answer:

27 J

Explanation:

We know that,

Potential Difference = Work done / Charge

Let work Done be w,

ATP,

Or, 9 = w / 3

Or, 27 = w

Hence, Work Done = 27 J.
