Variable Frequency Drive – a technology where the rotational speed of an electric motor is controlled or varied electronically.
The unit for reactive power Q.
The voltage drop across a resistance is the product of current time’s resistance (IR).
A two-terminal circuit element having an output voltage essentially independent of the current through it and characterized by a low internal resistance.
Voltage Dividers are used to supply two or more potentials to various parts of a circuit from the same power source.
The product VI, called apparent power, has the unit of volt-ampere (VA) and is indicated by the letter S.
A voltmeter is a basic device used for the measurement of electric potential or voltage, in volts.
The work required to move a unit charge in an electric field is defined as an electric potential.
