The current in `C` is `2 A`. The rate of heat of loss in `A,B` and `C are 1.20, 0.60 and `1.20 J//sec respectively. The emf of the cell [for cell internal resistance = 0] is

A

`3 V`

B

`1.5 V`

C

`3.6 V`

D

None

Text Solution

Verified by Experts

The correct Answer is:
B

(b) Power `= EI`
`implies (1.20 + 0.60 + 1.20) = E xx 2 implies E = 1.5 V`
