Question

What is the capacitive reactance of a capacitor?

विकल्प

• \[X_C=\frac{\omega}{C}\]

• \[X_C=\omega C\]

• \[X_C=\frac{1}{\omega C}\]

• \[X_C=\frac{C}{\omega}\]

Answer 1

A capacitor offers capacitive reactance \[X_C=\frac{1}{\omega C}\] to an AC source. Reactance increases when capacitance decreases at fixed angular frequency.
