Definitions:

Run Winding

The winding of a split-phase motor that remains energized during operation.

Resistors

Electronic components designed to introduce a specific amount of resistance to an electrical current, used in circuits to manage current flow.

Inductance

A property of an electrical conductor by which a change in current flowing through it induces an electromotive force both in itself (self-inductance) and in nearby conductors (mutual inductance).

Capacitors

Components in electrical circuits that store and release electrical energy, characterized by their capacitance value, which measures the ability to store charge per voltage unit.
