1. The problem statement, all variables and given/known data 2. Relevant equations V=IR H(w) = Y/F = Impedance of circuit 3. The attempt at a solution I wanted to simplify this circuit before I find any impedance, but I am not sure if I did my source transformation correctly. Can i combine the f(t) current source with the 1ohm in parallel even though there is another resistor in series with it? Or are my steps correct?
