Q1. Load factor of a power station is generally
(a) equal to unity
(b) less than unity
(c) more than unity
(d) equal to zero

S1. (B)
The value of load factor is usually less than 1. It is expected because average load on the power station is generally less than the maximum demand. If the average load on the power station is 80 MW and the maximum demand is 100 MW, then load factor = 80/100 = 0.8.

Q2. The average value of a sinusoidal current is 100 A. Its r.m.s value is ……….
(a) 63.7 A
(b) 70.7 A
(c) 141.4 A
(d) 111 A

S2. Ans.(d)
Sol. Rms value = 1.11 x average value
= 1.11 x 100= 111

Q3. A current wave is given by i = 4 + 2√2 sin 3θ + 4√2 sin 5θ. The r.m.s. value of current wave is ………
(a) 10 A
(b) 6 A
(c) √56 A
(d) 5 A

Q4. In general, fluid friction damping is not employed in indicating instruments although one can find its use in……………..
(a) dynamometer wattmeter
(b) hot-wire ammeter
(c) induction type energy meter
(d) Kelvin electrostatic voltmeter

S4. Ans.(d)
Most of the indicating instruments are portable. Fluid friction damping is not suitable because of the oil contained in the instrument.

Q5. Diversity factor is always
(a) equal to unity
(b) less than unity
(c) more than unity

S5. (C)
Diversity factor is the ratio of the sum of the individual maximum demands of the various subdivisions of a system (or part of a system) to the maximum demand of the whole system (or part of the system) under consideration. Diversity is usually more than one.
(d) more than twenty

Q6. Load curve is useful in deciding the
(a) operating schedule of generating units
(b) sizes of generating units
(c) total installed capacity of the plant
(d) all of the above

S6. (D)
Load curve helps in deciding
• total installed capacity of the plant
• sizes of the generating units
• operating schedule of generating units

Q7. The underground system cannot be operated above
(a) 440 V
(b) 11 kV
(c) 33 kV
(d) 66 kV

S7. (d)
66 KV, actually underground cable system is most suitable for those areas, where the neat and clean distribution is required. Mainly this type of wiring is seen in metro cities. The spaces in between the conductors are quite lesser as compared to overhead cables. So, strong insulation is provided with each cable. And after that, different layer of insulations is provided surrounding those cables. Considering all those things, 66 KV is considered as the highest voltage level for underground cable system.

Q8. Fig. shows voltmeter-ammeter method of measuring the value of resistance R. This method is used to measure R if its value is

(a) very low
(b) very high and moderate
(c) cannot say
(d) none of above

Q9. A hole and electron in close proximity would tend to…………….
(a) repel each other
(b) have no effect on each other
(c) attract each other
(d) none of the above

S9. Ans.(c)
There is a strong tendency of semiconductor crystal to form covalent bonds. Therefore, hole has a great attraction for electron so as to complete the bond.

Q10. The relation between β and α is ………
