Question

s Of Physics Class 12 Question 18. The reactance of a capacitor C is X. If both the frequency and capacitance be doubled, then new reactance will be
(a) X
(b) 2X
(c) 4X
(d) \frac{X}{4}

Answer 1

Answer:

$\frac{x}{4}$

Explanation:

Reactance is inversely proportional to (capacitance×frequency)

If both are doubled;

then new reactance is

$\frac{x}{4}$
