When a 50-$\mu$F capacitor is attached to an AC source, its capacitive reactance is 60 $\Omega$. If instead a 200-$\mu$F capacitor is attached to the same source, what will be its capacitive reactance?
A) 80 $\Omega$
B) 15 $\Omega$
C) 30 $\Omega$
D) 120 $\Omega$

Question

Quizplus · Accepted Answer

The capacitive reactance (Xc) is inversely proportional to the capacitance (C). If the capacitance is quadrupled from 50μF to 200μF, the reactance will be quartered. Therefore, 60Ω/4 = 15Ω.
