Assertion (A) :  One volt is the potential difference between two points in a current carrying conductor when 1 joule of work is done to move a charge of 1 coulomb from one point to the other.

Reason (R) : $\text{1 volt } = \frac{\text{1 joule}}{\text{1 coulomb}}$ 

Choose the correct option.

1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true, but R is not the correct explanation of A.
3. A is true, but R is false.
4. A is false, but R is true.

A

As : $\text{1 volt } = \frac{\text{1 joule}}{\text{1 coulomb}}$ 

This implies : 

One volt is the potential difference between two points in a current carrying conductor when 1 joule of work is done to move a charge of 1 coulomb from one point to the other.
