Asseration: The growth of current in `(R_L)` circuite is uniform.
Reason: Inductor `(L)` opposes the growth of current.

A

If both asseration and reason are true and reason is the correct explanation of assertion.

B

If both asseration and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D
The current in `R-L` circuit grows exponentiallly `I=I_(0)(1-e^(-Rt//L)).
