A cell of emf 2.0 V and internal resistance 0.1 `Omega` is connected with a resistance of 3.9`Omega`. The voltage across the cell terminals will be

A

0.50 V

B

1.90 V

C

1.95 V

D

2.0 V

Text Solution

Verified by Experts

The correct Answer is:
C

`V = (epsi R)/((R + r))= (2.0 xx 3.9)/((3.9 + 0.1)) = 1.95 V`
