Definitions:

RLC Parallel Circuit

An electrical circuit that contains a resistor (R), inductor (L), and capacitor (C) all connected in parallel, affecting the overall impedance differently from a series circuit.

Applied Voltage

The voltage that is applied across a component or circuit from an external source, driving current through it.

Parallel Resonant Circuits

Circuits where components are connected in parallel, bringing the circuit to resonance at a specific frequency where the inductive and capacitive reactances are equal in magnitude but opposite in phase.

Q

In electrical and electronic engineering, Q or quality factor refers to the measure of the efficiency of a reactive component, such as an inductor or capacitor, representing the ratio of stored vs. dissipated energy per cycle.
