The amount of energy expended during the passage of `1` ampere current for `100` sec under a potential of `115 V` :

A

20 kJ

B

11.5 kJ

C

115 kJ

D

0.115 kJ

Text Solution

Verified by Experts

The correct Answer is:
B
`Q=Ixxt=1xx100=100 C`
Energy = charge `xx` potential
`=100xx115=11500 J=11.5 kJ`
