Power attained in an AC circuit as a product of effective voltage and current which reach their peak at different times.

Measured in VA and is used in AC circuits when the load is not purely resistive having an inductive or capacative nature.

That power apparently available for use in an ac circuit containing a reactive element. It is the product of effective voltage times effective current expressed in volt-amperes. It must be multiplied by the power factor to obtain true power available.

Product of r.m.s. voltage and r.m.s. current. In an AC circuit with reactive components, this is not equal to the dissipated power, but an uncompensated power supply must nevertheless supply it.

The amount of power that is apparently consumed by a load. Apparent power is measure in VA or volt-amperes and is calculated by measuring the current consumed by the load and multiplying it by the voltage powering the load.

The mathematical product of the amperes times the volts in a current. Apparent power is composed of both real power (volts times the component of current in phase with the volts) and reactive power (volts times the component of current at right angles with the volts). Only real power is capable of doing work.

Volt-Amperes, VA. The product of voltage times current in a circuit including inductive and/or capacitive elements.

The product of the applied voltage and current in ac circuit. Apparent power, or volt-amps, is not the true power of the circuit since power factor is not considered in the calculation.

That power which is proportional to the mathematical product of the volts and amperes ( volt-amps) measured in a Circuit divided by 1,000. It is designated in kilovolt-amperes ( kVA) and is comprised of both "real" and "reactive" power.

Apparent power is the product of current and voltage, expressed as kVA. It is real power (kW) divided by the power factor (PF).

This is the voltage-ampere requirement of a device designed to convert electric energy to a non-electrical form.

The product of the voltage (volts) and the current amps. Comprises both active and reactive power. Measured in kVa or Mva.

Power value obtained in an ac circuit as the product of current times voltage. See VA.

The product of voltage and current in a circuit.

The product of RMS voltage and RMS current.

A term only applicable to Alternating Current (AC) circuits, it is the product of the voltage applied times the current flow. The unit of measure is VA, or Voltamperes.

The load power as expressed in VA or KVA. This value is usually greater than real power due to circuit reactance.

For single phase, the current in amperes multiplied by the volts equals the apparent power in volt-amperes. This term is used for alternating current circuits because the current flow is not always in phase with the voltage; hence, amperes multiplied by volts does not necessarily give the true power or watts. Apparent power for 3 phase equals the phase to neutral volts multiplied by ampere multiplied by 3.

A value of power for AC circuits that is calculated as the product of RMS current times RMS voltage, without taking the power factor into account.

Also called volt ampere or VA. The mathematical product of voltage and current on AC systems, which includes the effects of reactive power. Since voltage and current may not be in phase on AC systems, the apparent power thus calculated may not equal the real power, but may actually exceed it. Reactive loads (inductance and/or capacitance) on AC systems will cause the apparent power (VA) to be larger than the real power (watts). Apparent power can be graphically represented in vector form as the hypotenuse of a right triangle, where watts and reactive power represent the other two sides of the triangle. See Power factor. View illustration.

Calculated and theoretical power (watts) in an alternating current circuit. Apparent power is often grater than the actual power in a circuit because there are losses in the circuit due to the effect of reactance in the circuit. The reactance opposes the flow of AC current, using up some of the power.

The product of the voltage times the current, expressed in volt-amperes (VA). In purly resistive circuit it is the same as true power. Power stored in the field of a reactive component.
