Definitions:

Rectifies Current

The process of converting alternating current (AC) to direct current (DC), typically performed by a rectifier.

Field Coil

An electromagnet component used in electric motors and generators, responsible for creating a magnetic field when electrical current flows through it.

Full-Fielding Alternator

A method of maximizing an alternator's output by directly applying full battery voltage to its field coil.

A-B Type Circuit

A type of electrical circuit configuration that may involve specific path setups for current flow or a particular application's circuit design, but further specific context is needed for a precise definition.
