The capacitive reactance of a load is directly-proportional to
A) the supply voltage
B) the supply voltage.
C) its capacitance

Question

Quizplus · Accepted Answer

Capacitive reactance (Xc) is given by the formula Xc = 1/(2πfC), where f is the frequency and C is the capacitance. As we can see, Xc is directly proportional to capacitance C. Therefore, the best choice is C. The supply voltage will affect the magnitude of current through the load, but it will not directly affect the capacitive reactance of the load. So, choices A and B are incorrect.
