Question

In an alternator, which of the following makes an electrical connection to the rotor field coil to supply current from the voltage regulator?

a) Brushes/slip rings
b) Bearings
c) Stationary coils
d) End frames

Answer 1

In an alternator, the brushes/slip rings make an electrical connection to the rotor field coil to supply current from the voltage regulator.

Step-by-step explanation:

In an alternator, the brushes/slip rings make an electrical connection to the rotor field coil to supply current from the voltage regulator.

The brushes are made of carbon or graphite and are in constant contact with the slip rings, which are metal rings attached to the rotor. When the rotor spins, the brushes maintain contact with the slip rings, allowing current to flow into the rotor field coil.

This electrical connection is essential for the generator to produce electricity.
