Definitions:

R

A symbol often used to represent resistance in electrical circuits.

Phase Angle

A measurement, often in degrees or radians, that describes the difference in phase between two waveforms, significant in AC circuits and signal processing.

RC Parallel Circuit

An electrical circuit consisting of resistors (R) and capacitors (C) connected in parallel, affecting the total impedance and phase angle.

R

Often used as a symbol for resistance in electrical circuits, measured in ohms (Ω).
