Definitions:

Applied Voltage

The external voltage that is applied to an electrical device or circuit, which drives the current flow through it.

Bandwidth

The range of frequencies within a given band, particularly used in reference to the transmission capacity of a network or the passband of a filter.

Parallel LC Circuit

A circuit configuration that contains both inductance (L) and capacitance (C) in parallel, which can exhibit resonance at a specific frequency where reactive effects cancel each other.

Impedance

A measure of the total opposition that a circuit presents to alternating current, including both resistance and reactance.
