Question

(e) A charge is taken from a point A to a point B, the work done per unit charge in the process is
called
3. The potential difference between B and A
1. The potential at A 2. potential at B
4. The current from A to B​

Answer 1

potential difference
I Hope You understand

Answer 2

Answer:

3. The potential difference between B and A

Explanation:

When a unit charge placed at a fixed point A and it is moved to another point B against and external field, then the work done by the external force to do so is called the electric potential difference between the two points A and B.  

So, the right answer is option 3.

If the work done is negative, the potential difference will be negative.

If the work done is positive, the potential difference will be positive.
