 Now that we have briefly seen what comprised the AC, let's powers, since it is the subject of this article. So there are 3 different powers, we will see in more detail later, ie the apparent power, active and reactive.
All three are linked by the triangle of power.
    Apparent power:
 Apparent power is the sum (trigonometric) of active and reactive power. It is also the contracted power (kVA) for ERDF subscription. It is calculated as follows:

 S = iu
 S = Apparent power (VA) (homogeneous in Watts)
 U = Voltage (V)
 I = Current (A)

   Apparent power ...
