Definitions:

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.

Capacitive Reactance

The opposition that capacitors present to the change of voltage in AC circuits, inversely related to the frequency of the current and the capacitance.
