What is reactive power and why does it matter?

Reactive power is a function of a system''s amperage, and it is not consumed in the circuit, it is all returned to the source, which is why reactive power is often described as energy that moves back and forth within a circuit. In this sense it is not "active" or "real" since it is not used to carry out work such as powering a light.
