Definitions:

High-pass Filter

An electronic filter that allows frequencies higher than its cutoff frequency to pass through while attenuating frequencies lower than the cutoff frequency.

Load Resistor

A resistor used in a circuit to simulate an electrical load, typically for testing purposes or to dissipate energy.

Resonant Frequency

The frequency at which a system naturally oscillates with maximum amplitude, such as in electrical circuits or mechanical systems.

Low Impedance

A characteristic of a circuit that allows a large amount of current to flow due to its low opposition to the current flow.
