Switch `S` shown in Fig. is closed for `t lt 0` and is opened at `t = 0`. When currents through `L_(1)` and `L_(2)` are equal, their common value is

A

`(E)/(R )`

B

`(E(L_(2) + L_(2)))/(RL_(1))`

C

`(EL_(1))/(R(L_(1) + L_(2)))`

D

`(E)/(R ) ((L_(1) + L_(2)))/(L_(2))`

Text Solution

Verified by Experts

The correct Answer is:
C
Constancy of flux implies that `(E)/(R ) L_(1) = i(L_(1) + L_(2))`
i.e., `i = (EL_(1))/(R(L_(1) + L_(2))`
