Definitions:

Series

Components in an electrical circuit are said to be in series if they are connected along a single path, so the same current flows through all of the components.

Inductive Reactance

The opposition to alternating current flow due to the inductance of a component or circuit, measured in ohms.

Reactive Power

Also called wattless power. Calculated by multiplying reactive voltage by reactive current. Can be produced by inductive or capacitive loads.

Inductive Reactance

The opposition an inductor provides to alternating current, directly proportional to the frequency of the current.
