Regulation

The measure of how well a power generator maintains constant voltage over a range of load currents is called voltage regulation. It can be calculated from the following formula:

$R e g percent sign equals 100 asterisk times fraction numerator V subscript n o space l o a d end subscript space minus space V subscript f u l l space l o a d end subscript over denominator V subscript f u l l space l o a d end subscript end fraction$

Relay

Is an electrically operated switch

Resistance

Resistance is the opposition that a substance offers to the flow of electric current.

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.
