see under impedance.

Reactive Power

Reactive power is sometimes called Quadrature Power.

$Q equals S space sin empty set$

$Q equals square root of S squared minus P squared end root$

Q equals V squared over X subscript c

Resonance

This is what happens when inductive reactance and Capacitive reactance cancel each other out because they are the same as each other.

Resonant Frequency

The frequency produces Inductive Reactance that is equal to Capacitive Reactance, both in a series circuit and also for a parallel circuit.

In a series circuit, it will result in the highest current for the circuit and voltages across the capacitor and inductor that may be much higher than the supply voltage.

Resultant Current

The sharing of current between different components in an AC circuit

Keyword(s):

RMS

The square root of two, divided by two.
