Electrical Engineering : Circuits And Circuit Theory QUESTIONS AND ANSWERS :: part2 : 6 to 10

Following Electrical Engineering Multiple choice objective type questions and answers will help you in BSNL JTO, GATE 2024 and IES 2024 examinations :

6.In any A.C. circuit always

apparent power is more than actual power
reactive power is more than apparent power
actual power is more than reactive power
reactive power is more than actual power

7.The power factor at resonance in R-L- C parallel circuit is

zero
0.08 lagging
0.8 leading
unity

8.Power factor of the system is kept high

to reduce line losses
to maximise the utilization of the capacities of generators, lines and transformers
to reduce voltage regulation of the line
due to all above reasons

9.In series resonant circuit, increasing inductance to its twice value and reducing capacitance to its half value

will change the maximum value of current at resonance
will change the resonance frequency
will change the impedance at resonance frequency
will increase the selectivity of the circuit

10.Time constant of an inductive circuit

increases with increase of inductance and decrease of resistance
increases with the increase of inductance and the increase of resistance
increases with decrease of inductance and decrease of resistance
increases with decrease of inductance and increase of resistance
