**Answer:** **Active Power,** it is the true power which is actually consumed in the circuit. We can say that it is the product of voltage and current and power factor.

** Reactive power:** It is the product of voltage current and sin of the phase angle.

**Apparent power:** It is the product of voltage and current.

**Real Power: (P)**

**Real Power** is the actual power which is really transferred to the load such as transformer, induction motors, generators etc.

**Reactive Power: (Q)**

Also known as (**Use-less Power**, **Watt less Power**)

The powers that continuously bounce back and forth between source and load is known as reactive Power (**Q**).

**Apparent Power: (S)**

The p**roduct of voltage and current** if and only if the **phase angle differences**between current and voltage are ignored.

Total power in an AC circuit, both dissipated and absorbed/returned is referred to as apparent power.
