Problem: A RL circuit is driven by an AC generator as shown in the figure.The phase difference between the CURRENT through the resistor and inductor ___________.A. is always zeroB. is always 90°C. depends on the value of L and RD. depends on L, R, and the generator voltageBriefly explain you reasoning.

Current:

$\boxed{\mathbf{i}\mathbf{=}\frac{\mathbf{v}}{\mathbf{R}}}$

The phase difference between the inductor and the resistor remains constant at 90°.

Since the circuit is the same, it will be the same current.
