Description : The induced e.m.f. in the armature conductors of a d.c. motor is?

Answer : The induced e.m.f. in the armature conductors of a d.c. motor is sinusoidal.

Answer : In a A.C. series motor armature coils are usually connected to commutator through resistance.

Answer : In any rotating machine that part which houses the conductors and in which e.m.f. induced is to be utilised is called armature.

Answer : Armature coil is short circuited by brushes when it lies along neutral axis.
