Question

Which are listed as sources of mechanical energy supplied to the rotor shaft?

Options

• Steam, water from a dam, and wind

• Iron core, copper wire, and carbon

• Slip rings, carbon brushes, and resistance

• Magnetic flux, EMF, and alternating current

Answer 1

Mechanical energy can be supplied to the rotor shaft by steam, water from a dam, or wind. That input drives the rotation needed for electromagnetic induction.
