Definitions:

Frequency Source

A device or circuit component that generates an oscillating electrical signal of a specific frequency.

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.
