Comparison of True Versus Reactive Power
When a resistive load is connected, no phase shift is occurs between the voltage and current.
The Power that is the result of the resistive load performs work in the circuit. This is known as “true” power, and is measured in watts.
By comparison, an inductive load causes a 90-degree phase shift between voltage and current.
To calculate the power that results from an inductive load, multiply voltage by current. When either voltage or current is zero, the power is zero. This type of power is known as “reactive” power. It counteracts the true power in an electrical circuit. It is measured in reactive volt-amperes.
