2. The critical frequency for an RL circuit occurs at the frequency at which the resistance is equal to the inductive reactance (R = XL). Since XL = 2πfl, for an inductor, it can be shown that the circuit frequency for an RL circuit is ferit = R 2πL Calculate the critical frequency for the experiment. What is the phase angle between VR and Vs at the critical frequency?
