Definitions:

Applied Voltage

The electrical potential difference deliberately introduced to a circuit or device.

Capacitive Reactance

The opposition that a capacitor offers to alternating current (AC), which decreases as the frequency of the AC increases, calculated as 1/(2πfC) where f is the frequency and C is the capacitance.

Series Connection

A circuit configuration in which components are connected end-to-end, providing a single path for current flow.

Frequency Source

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