A cell of emf `epsilon` and internal resistance r is charged by a current I, then

A

the cell stores chemical energy at the rate of `epsiloni`

B

the cell stores chemical energy at the rate of `i^2r`

C

the cell stores chemical energy at the rate of `epsilon I - i^2r `

D

the storage of chemical energy rate cannot be calculated

Text Solution

Verified by Experts

The correct Answer is:
C
c. From work-energy theorem, we get `Delta = epsiloni - i^2r`.
