At t = 0, switch S is closed (shown in F...

At `t = 0`, switch `S` is closed (shown in Fig.). After a long time, suddenly the inductance of the inductor is made `eta` times lesser `(L//eta)` than its initial value. Find out current just after the operation.

Text Solution

Verified by Experts

`i_(1) = (varepsilon)/(R ),L_(1) i_(1) = L_(2)i_(2) rArr i_(2) = (eta varepsilon)/(R )`
