I am stuck on this...
Given a circuit: current source (Is(t)), R , C - all parallel; Is(t) = e^jt, Vs(t) = 223.6e^j(t - 63.43), Vs(t) is voltage across the current source, which I assume to be the same across R and C since they are ||.
Find R and C. (ans: 500 Ohm, 4mF)
My attemp was to use source transformation and get R from it, but it did not match the answer.
I.e. I tried to make a circuit all series by source transformation: V = IR, so given Vs(t) and Is(t) , R = 223.6e^(-j63.43) and that does not turn out to be 500 Ohm :grumpy:
Another way I am thinking is that Vs(t) is the response on the C, so I will have to work backwards from the equations for phase and Vm (response magnitude).
Any help on this is GREATLY appreciated...this is as clear as mudd...
