Here to find Zth vs short-circuit and RL open circuit. R1 parallel with Xl.
Zth= 220*47i/220+47i.
=45.96∠77.94.
Zth= 220*47i/220+47i.
=45.96∠77.94.

But w.r.t AB, XL and R1 should be in series.
So the answer should be A.
So the answer should be A.

Where did you get 220?

Here parallel combination of R1 = 220 and XL will give the answer.

Hi,
Since the source has 0Hz then it acts as a DC voltage source. Shouldn't the inductor act as a short circuit?
