Frequency Source
An electronic component or circuit that generates a specific frequency or range of frequencies, often used in telecommunications and signal processing.
Capacitive Reactance
The measure of a capacitor's opposition to changes in voltage, affecting AC flow without dissipating energy, inversely proportional to the frequency.
Series Connection
A type of circuit configuration where components are connected end-to-end, and the current flows through one component to get to the next.
