A 12 V lead accumulator is being charged using 24 V supply with an external resistance `2 Omega` . The internal resistance of the accumulator is `1 Omega` . Find the time in which it will store 360 W -hour energy.

A

1 hr

B

7.5 hr

C

10 hr

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
`I =(24-12)/3 = 4A, t = 360/(VI) = 360/(12 xx 4) = 7.5` hours
