Definitions:

RC Parallel Circuit

An electric circuit in which a resistor and a capacitor are connected parallelly, affecting the impedance and the phase of the voltage and current.

R

Symbol typically representing resistance in electrical circuits, quantifying how much a material opposes the flow of electric current.

Apparent Power

The total power in an AC circuit, measured in volt-amperes, combining both active (real) and reactive power components.

RC Parallel Circuit

A type of electrical circuit combining resistors and capacitors in parallel configuration, which influences the total impedance and phase angle.
