Find the total heat produced in the loop...

Find the total heat produced in the loop of the previous problem during the interval 0 to 30 s if the resistance of the loop is `4.5 Omega`.

A

`2.5xx10^(4)J`

B

`2.0xx10^(4)J`

C

`3.0xx10^(4)J`

D

`3.5xx10^(4)J`

Text Solution

Verified by Experts

The correct Answer is:
B
The current exists in the loop for time-interval `t=0` to `t=5s` and `t=20` to `t=25s` i.e., for time `t=10sec`
`H=(e^(2))/(R)t=(3xx10^(-4))xx10/(4.5xx10^(-3))=2xx10^(-4)J`
