Question

Which best contrasts an electric generator and an electric motor?

In a generator, slip rings function as a solenoid, and in a motor, an armature functions as a solenoid.
In a motor, slip rings function as a solenoid, and in a generator, an armature functions as a solenoid.
A generator converts electrical energy to kinetic energy, and a motor converts kinetic energy to electrical energy.
A generator converts kinetic energy to electrical energy, and a motor converts electrical energy to kinetic energy.

Answer 1

A generator converts kinetic energy to electrical energy, and a motor converts electrical energy to kinetic energy.

(Generators use mechanical rotation to induce an emf; motors use current in magnetic fields to produce torque. The slip-ring/armature statements are incorrect.)
