Definitions:

Capacitive Reactance

The opposition to change in voltage across a capacitor, inversely proportional to the frequency of the applied AC signal and the capacitor's capacitance.

Frequency

The number of times a periodic event repeats in a given time unit, often used to describe the rate at which alternating current cycles, measured in hertz (Hz).

Pure Capacitive Circuit

An electric circuit that contains only a capacitor, which stores electrical energy in an electric field, showing ideal capacitive behavior without resistance or inductance in the circuit.

Applied Voltage

The external voltage provided to an electrical component or circuit.
