The capacitor C is initially without charge. X is now joined to Y for a long time, during which `H_1` heat is produced in the resistance R. X is now joined to Z for a long time, during which `H_2` heat is produced in R

A

`H_(1)=H_(2)`

B

`H_(1)=H_(2)//2`

C

`H_(1)=2H_(2)`

D

the maximum energy stored in `C` at any time is `H_(2)`

Text Solution

Verified by Experts
