Definitions:

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.

Voltage

The difference in electric potential between two points in a circuit, measured in volts.

RLC Parallel Circuit

An electrical circuit consisting of a resistor (R), inductor (L), and capacitor (C) connected in parallel, used to analyze resonance and filtering applications.

Currents

The flow of electric charge in a conductor, typically measured in amperes, representing the rate at which electric charge is flowing.
