Time: 06 min.

Q1. Which method is used for transferring the power through an auto transformer?
(a) Mutual coupling
(b) Induction
(c) Conduction
(d) Induction and conduction

Q2. The no-load current drawn by a transformer is usually ……… of the full-load current.
(a) 15 to 20 percent
(b) 2 to 5 percent
(c) 0.2 to 0.5 percent
(d) 10 to 15 percent

Q3. In which of the following starters is No Volts Coil (NVC) connected in series with the field coil?
(a) Two-point starters
(b) Five-point starters
(c) Three-point starters
(d) Four-point starters

Q4. ……is an example of a passive transducer.
(a) Piezoelectric
(b) Thermocouple
(c) Electromagnetic pickup
(d) Linear variable differential transformer (LVDT)

Q5. A dc series motor drawing an armature current of I_a is operating under saturated magnetic conditions, torque developed in the motor is proportional to
(a) 1/Ia
(b) 1/Ia^2
(c) Ia^2
(d) Ia

Q6. Fusing factor of fuse is always
(a) More than 1
(b) Less than 1
(c) Infinity
(d) Zero

SOLUTIONS

S1. Ans.(d)
Sol. In an autotransformer, power is transferred through both conduction and induction processes.
For 3-phase Transformer, power is transferred through induction only.

S2. Ans.(b)
Sol. 2 – 5 %.

S3. Ans.(c)
Sol. The handle is held in RUN position by an electromagnet energized by a no-volt trip coil (NVC). This no-volt trip coil is connected in series with the field winding of the motor.

S4. Ans.(d)
Sol.
Active transducer: Piezoelectric, thermocouple, PV cell.
Passive transducer: LVDT

S5. Ans.(d)
Sol. We know Torque Tα ΦIa, As the motor is operating under saturation condition so torque will be independent of flux i.e., T α Ia.

S6. Ans.(a)
Sol. Fusing factor=(minimum fusing current)/(current rating of fuse)
Fusing factor of fuse is always >1.
