Can anyone help me find the input resistance of the circuit? I have been stuck for many hours and can't solve it.
I find the equivalent resistance of the circuit by applying a voltage source at the input and solve for the current I.
The input resistance:
Rin = V/I
However, I don't know why this method doesn't work. Rin is always a function of V and that is not right.
