A three phase semiconverter leeds the arrnare of a separately excited dc motor, SUpplying a non-zero torque. For steady state operation, ti motor armature current is found to drop to zero at certain instances of time. At such in the votage assumes a value that is

(a) equal to the instantaneous value of th dc phase voltage
(b) equal to the instantaneous value of the motor back emi.
(c) arbitrary
(d) zero.

A thyristorised, three phase, fully contro1l converter feeds a dc load that draws a constant current. Then the input ac line current to the converter has

(a) an rms value equal to the dc load current
(b) an average value equal to the dc load current
(c) a peak value equal to the dc load current
(d) a fundamental frequency component, who rms value is equal to the dc load current.

A 3-phase, 4-pole squirrel cage induction motor has 36 stator and 28 rotor slots. The number ol phases in the rotor is

(a)3
(b)9
(c)7
(d)8

The compensating winding in a dc machine

(a) is located in armature slots for compensation of the armature reaction
(b) is located on commutating poles for improving the commutation
(c) is located on pole shoes for avoiding the Ilashover at the commutator surface
d) is located on pole shoes to avoid the sparking at the brushes.

In a constant voltage transformer (CVT), the output voltage remains constant due to

(a) capacitor
(b) input inductor
(c) saturation
(d) tapped windings

The phase sequence of a three-phase alternator will reverse if

(a) the field current is reversed keeping the direction of rotation same
(b) the field current remains the same but the direction of rotation is reversed
(c) the field current is reversed and the number of poles is doubled
(d) the number of poles is doubled without reversing the field Current.
