A 17.0-μF capacitor is connected to an AC source with an rms voltage of 120 V and a frequency of 60.0 Hz.What is the rms current in the capacitor?
A) 1.41 A
B) 0.543 A
C) 0 A
D) 0.769 A

Question

Quizplus · Accepted Answer

The rms current in a capacitor connected to an AC source is given by:
Irms = Vrms/ωC
where Vrms is the rms voltage of the source, ω is the angular frequency (2πf), and C is the capacitance of the capacitor.
Substituting the given values, we get:
Irms = 120 V / (2π x 60 Hz x 17.0 x 10^-6 F)
Irms ≈ 0.769 A
Therefore, the correct answer is (D) 0.769 A.
