An inductor having self inductance L wit...

An inductor having self inductance L with its coil resistance R is connected across a battery of emf `epsilon`. When the circuit is in steady state t = 0, an iron rod is inserted into the inductor due to which its inductance becomes `nL (ngt1)`.

When again circuit is in steady state, the current in it is

A

Increases with time

B

Decreases with time

C

Remains constant with time

D

First decreases with time then becomes constant

Text Solution

Verified by Experts

The correct Answer is:
A
Even after insertion of the rod the current in circuit will increase with time till steady state is reached.
