70ᵗʰ B.P.S.C Re-Exam 2024
Reactance of a capacitor is :
aDirectly proportional to frequency
bInversely proportional to sq. root of frequency
cInversely proportional to frequency✓ Correct
dNone of the above
Explanation
The reactance of a capacitor is inversely proportional to fre- quency. $$X_c = \frac{1}{\omega C}$$ $$X_c = \frac{1}{2\pi FC} \ ( \cdot : \ (i) = \pi f)$$ $$\omega C\,3\ \frac{1}{f}$$ ## Page 23
