Question

Potential difference across the terminals of the battery shown in figure is - ($r=$ internal resistance of batter)

• A. $8V$
• B. $10V$
• C. $6V$
• D. $Zero$

Answer 1

The correct option is D $Zero$

Potential difference (V) is measured in volts (V). Potential difference is the work done per unit charge. A potential difference of 1 V means that 1 joule of work is done per coulomb of charge. Potential difference is the work done in moving a unit of positive electric charge from one point to another. In this case No work is done So Potential Difference is zero
