we are studying generators.
ac generators make perfect sense. rotor windings are energies with dc via slip rings and when spun produce an alternating current in the stator. also this process can be reversed. if dc is applied to the stator and the rotor is spun then an alternating current is retrieved from the rotor windings via the slip rings.
a basic dc generator also makes sense. dc is applied to the stator and when the rotor is spun direct current is retrieved from the rotor via the commutator. the commutator acts as mechanical rectifier.
where i'm not sure is... if dc is applied to the rotor via the commutator and the rotor is spun what happens in the stator? will it make ac, dc, or nothing at all?
