a) What is the maximum current in a 4.00 µF capacitor when it is connected across a North American electrical outlet having ΔVrms = 120 V, f = 60.0 Hz?

Question

mA
(b) What is the maximum current when it is connected across a European electrical outlet having ΔVrms = 240 V and f = 50.0 Hz?

Answer 1

a. Xc = 1/2pi*F*c
Xc = 1/(6.28*60*4*10^-6) = 663.5 Ohms.

I = V/Xc = 120/663.5 = 0.181A rms.

b. Same procedure as "a".
