A capacitor of capacitance 25 F is connected to... - WAEC Physics 1997 Question
A capacitor of capacitance 25µF is connected to an a.c power source of frequency 200/πHz. Calculate the reactance of the capacitor
A
0.01Ω
B
0.02Ω
C
50Ω
D
100Ω
correct option: d
(X_c=\frac{1}{2\pi{fc}})=(\frac{1}{2\times\pi\times\frac{200}{\pi}\times 25\times 10^{-6}}=\frac{10^6}{10^4})=100 Ω
