Chapter 30, Problem 1PLA

To determine

The definition of capacitive reactance.

Answer to Problem 1PLA

Capacitive reactance is inversely proportional to the angular frequency and the capacitance of the capacitor.

Explanation of Solution

Capacitive reactance is the measure for the opposition of current flow. It is inversely proportional to the angular frequency and the capacitance of the capacitor.

Write the formula for capacitive reactance

    $X_C=\frac{1}{\omega C}$

Here, $X_C$ is the capacitive reactance, $\omega$ is the angular frequency of the AC generator and $C$ is the capacitance of the capacitor.

Conclusion:

Capacitive reactance is inversely proportional to the angular frequency and the capacitance of the capacitor.
