Question

What happens to the capacitive reactance if the frequency is doubled while capacitance stays the same?

विकल्प

• The capacitive reactance is doubled.

• The capacitive reactance is halved.

• The capacitive reactance becomes zero.

• The capacitive reactance is unchanged.

Answer 1

Capacitive reactance is \[X_C=\frac{1}{2\pi\nu C}\]. Doubling \[\nu\] while keeping \[C\] fixed halves \[X_C\].
