2 V

3 V

4 V

Text Solution

Verified by Experts

The correct answer is:

Resistance of the upper arm

Resistance of the lower arm

As the resistance of both arms are equal, therefore same amount of current flows in both the arms.

Current through each arm CAD or CBD = 1 A

Potential difference across C and A is

….(i)

Potential difference across C and B is

….(ii)

Subtracting (i) from (ii), we get
