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 imaginary portion.) Attempt: 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?
