Quizplus · Accepted Answer

The phase angle of the impedance in an electrical circuit is determined by the relationship between the resistive (R) and reactive (X) components. When the reactive component (inductive or capacitive) leads or lags the resistive component, it results in a positive or negative phase angle, respectively. A phase angle of -45° typically indicates an equal magnitude of resistance and reactance in a circuit, leading to a situation where the voltage and current are out of phase by 45 degrees, with the current lagging in the case of an inductive circuit or leading in a capacitive one.
