The question is:
The voltage source in the above circuit is a sinusoidal AC source with constant amplitude and constant phase shift but an adjustable frequency.
Calculate the frequency ω at which the phasor current I will have zero phase shift relative to the
voltage source. In other words, the equivalent impedance across the voltage source behaves like a
pure resistance with zero reactance at the required frequency.
(HINT: Given two complex numbers such that A + jB = C + jD, then A = C and B = D by inspection,
i.e. the real portion must equal the real portion and the imaginary portion must equal the
Since it stated that the reactance is zero, that means Z = R. So Req = (1/100+1/100)^-1 = 50. I converted the v(t) into V (phasors) which become 100. Then I = V/R, so I get 100/50 = 2. I don't know what to do next. Am I even doing it correctly?
