Question

If the cell is short circuited, its terminal potential difference is

• A. zero
• B. unity
• C. infinity
• D. none of these

Answer 1

The correct option is A

zero

1. The relationship between the potential difference and current is given by, $V=IR$ Where,$V$ is potential difference, $I$ is current, $R$ is resistance.
2. As we see in the above equation when the value of current is $0$, a potential difference $V$ is also going to be $0$.
3. When a cell has short-circuited the value of current in the circuit becomes $0$, and along with the current potential difference also becomes $0$.
4. Therefore, If the cell is short-circuited, its terminal potential difference is zero.

Hence, option (A) is correct.
