Question

The inductive reactance of the circuit is exactly twice the resistance: XL=2R. Adjust the phasor that represents the voltage across the inductor (VL) at the instant indicated to the proper length and orientation.

Answer 1

The inductive reactance of a circuit is given by XL = 2πfL, where XL is the inductive reactance, f is the frequency of the AC voltage source, and L is the inductance. In this case, the inductive reactance is exactly twice the resistance, so XL = 2R. To adjust the phasor that represents the voltage across the inductor (VL), we need to determine the correct length and orientation.
