Question

Quizplus · Accepted Answer

The superposition theorem involves analyzing a linear circuit with multiple sources by "turning off" all but one source and calculating the effect of the active source on the circuit. The current through the capacitor due to the 10 V 20° voltage source can be calculated by considering the impedance of the capacitor and any series or parallel resistances or inductances in the circuit. The correct answer, A) 0.822 A 29.5°, likely results from applying Ohm's Law (V=IZ) to the circuit with the given voltage source and the impedance of the capacitor at the frequency of interest, taking into account the phase shift introduced by the capacitor.
