Question

What happens to the capacitive reactance when the capacitance is reduced at a fixed angular frequency?

Options

• The capacitive reactance becomes zero.

• The capacitive reactance increases.

• The capacitive reactance is unchanged.

• The capacitive reactance is halved.

Answer 1

Capacitive reactance is \[X_C=\frac{1}{\omega C}\]. At fixed \[\omega\], reducing \[C\] increases \[X_C\].
