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.
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 zero
B. is always 90°
C. depends on the value of L and R
D. depends on L, R, and the generator voltage
Briefly explain you reasoning.
