How much current flows through the brushes and slip rings of an alternator?

A) the combined rated CCA current of the batteries
B) full output of the alternator
C) field current
D) whatever current can pass through the voltage regulator

Field Current

The electric current that flows through the winding of a generator or motor, generating a magnetic field necessary for their operations.

Brushes

Stationary devices used to conduct current to or from a rotor in electrical components such as alternators and motors.

Slip Rings

Stationary devices used to conduct current to an alternator rotor.
