Parameters

voltage IPhasorValue: Voltage phasor.
current IPhasorValue: Current phasor.

Return Value

Power
Calculated vars (total volt-amperes of reactive power) from imaginary and real components of specified voltage and current phasors.

Exceptions

Exception	Condition
ArgumentNullException	voltage and current must not be null.

Remarks

Although the Power units class technically represents watts (i.e., real power) and vars (i.e., imaginary power) are properly expressed in volt-amperes reactive (VAr), the calculated result is still a representation of power and therefore the Power units class is used to express the return value leaving the consumer to properly apply the needed engineering units for display purposes.
