Assertion (A): Thevenin's theorem helps us to find current in a branch of a network for different values of impedances of that branch.

Reason (R): Thevenin's equivalent circuit replaces a network by a voltage source in series with impedance.

Both A and R are true and R is correct explanation of A
Both A and R are true and R is not the correct explanation of A
A is true but R is false
A is false but R is true
