Question

Capacitive reactance of a capacitor in an A C circuit is 3 kΩ . If this capacitor is connected to a new A C source of double frequency, the capacitive reactance will become, 1 . 5 kΩ, 3 kΩ, 6 kΩ, 5 . 2 kΩ

MARKS App · Accepted Answer

Capacitive reactance is given by, X c = 1 2 π f C . Clearly, if the frequency of the AC source is doubled then capacitive reactance will be halved, which is 1 . 5 kΩ .
