Answer : When two D.C. series motors are connected in parallel, the resultant speed is normal speed.
Answer : During rheostat braking of D.C. series motors motor is run as a generator.
Answer : In a capacitor start and run motors the function of the running capacitor in series with the auxiliary winding is to improve power factor.
Answer : In case of D.C. shunt motors the speed is dependent on back e.m.f. only because flux is practically constant in D:C. shunt motors.
