typedef Standard_Real  Quantity_Power 
Defined as the rate of expending energy or doing work. In mechanical terms it is the product of a force and the distance it moves per unit time. In electrical terms it is the product of the voltage and the current. For AC the rootmeansquare values are multiplied by the cosine of the phase angle. It is measured in watts (joules per second).
