Hello. I've been doing problems, and transforming from time domain to phasor domain to find input impedances seems simple enough But I've come across a circuit with a dependent voltage source, as shown in the above figure, and I'm not sure how to approach it. Must a voltage be assumed?
With the assumption, a voltage across the 5ohm resistor is obtained as well as the dependent source. But does that make the value in the dependent source an impedance as well? Thank you for your time.
