When a 60-Hz voltage is applied to a 22-μF capacitor, the capacitive reactance is A)121 Ω. B)760 Ω. C)13 × 10^-4 Ω. D)510 Ω. E)83 × 10^-4 Ω.

Question

Quizplus · Accepted Answer

The capacitive reactance (Xc) is calculated using the formula Xc = 1 / (2πfC), where f is the frequency (60 Hz) and C is the capacitance (22 μF = 22 × 10^-6 F). Plugging in the values, Xc = 1 / (2π × 60 × 22 × 10^-6) ≈ 121 Ω.
