Definitions:

RC Parallel Circuit

An electrical circuit that consists of resistors (R) and capacitors (C) connected alongside each other in parallel, allowing for AC filtering or timed circuits.

R

In electrical engineering, "R" typically refers to resistance, which is a measure of the opposition to the flow of electric current.

Apparent Power

The product of the current and voltage in an AC circuit, measured in volt-amperes, not necessarily equal to the actual power consumed.

RC Parallel Circuit

An electrical circuit in which a resistor and a capacitor are connected in parallel, affecting the impedance and phase angle of the overall circuit.
