Definitions:

Reactance Value

A measure of the opposition that a circuit presents to a change in voltage or current due to its capacitance or inductance.

Frequency

The number of complete oscillations or cycles per unit of time, typically measured in hertz (Hz).

Countervoltage

A voltage that opposes the primary voltage source in a circuit, often referred to as back EMF (Electromotive Force).

Capacitive Reactance

The resistance that a capacitor offers to the flow of alternating current (AC) in an electrical circuit, which varies inversely with the frequency of the current and the capacitance of the capacitor.
