Definitions:

RC Parallel Circuit

An electrical circuit composed of resistors (R) and capacitors (C) connected in parallel, affecting the total impedance seen by an alternating current (AC) source.

R

A symbol commonly used to represent resistance in electrical circuits, measured in ohms (Ω).

Reactive Power

The portion of electricity that oscillates between the source and load in an AC system, essential for maintaining the voltage to deliver active power (work) but itself does no work.

RC Parallel Circuit

A circuit configuration where a resistor (R) and a capacitor (C) are connected alongside each other and share the same two nodes, resulting in a specific impedance.
