In the current shown Fig., `X` is joined to `Y` for a long time and then `X` is joined to `Z`. The total heat produced in `R_(2)` is

A

`(LE^(2))/(2R_(1)^(2))`

B

`(LE^(2))/(2R_(2)^(2))`

C

`(LE^(2))/(2R_(1)R_(2))`

D

`(LE^(2)R^(2))/(2R_(1)^(2))`

Text Solution

Verified by Experts

The correct Answer is:
A
`U=1/2LI_(0)^(2)=1/2 L xx(E/R_(1))^(2)=(LE^(2))/(2R_(1)^(2))`
`H=Uimplies H=(LE^(2))/(2R_(1)^(2))`
