For a cell, a graph is plotted between the potential difference V across the terminals of the cell and the current I drawn the cell. The emf and the internal resistance of the cell are E and r, respectively. Then

A

`E = 2V, r = 0.5 Omega`

B

`E = 2V, r = 0.4 Omega`

C

`E gt 2 V, r = 0.5 Omega`

D

`Egt2 V, r = 0.4 Omega`

Text Solution

Verified by Experts

The correct Answer is:
B
The bridge is balanced and the current is ADC is larger then in ABC, Also `I_(3) = 0.`
