MCQ – Basic Electrical – Set III

1. Cells are connected in series in order to increase the

  • current capacity
  • life of the cells
  • voltage rating
  • terminal voltage

2. Cells are connected in parallel in order to increase

  • life of the cells
  • efficiency
  • current capacity
  • voltage rating

3. When two cells are connected in parallel , it should ensure that have

  • identical internal resistances
  • equal emfs
  • same ampere hour capacity

4.The capacity of a battery is expressed in

  • amperes
  • amperes-hour
  • watts
  • watt-hour

5. A series resonant circuit implies

  • zero pf and maximum current
  • unity pf and maximum current
  • unity pf and minimum current
  • zero pf and minimum current

6. which one is classified as integrating instrument?

  • D’arsonval galvanometer
  • Ampere-hour meter
  • ohm-meter
  • ammeter

7. Which of the following types of instrument is an integrating instrument?

  • power factor meter
  • energy meter
  • watt meter
  •  frequency meter

8. Voltmeter should be of very high resistance so that

  • its range is high
  • its accuracy is high
  • it may draw current minimum possible
  • its sensitivity is high

9. If a voltmeter is connected like a ammeter in series with a load

  • the measurement reading will be too high
  • almost no current will flow in the circuit
  • the meter will burn out
  • an inadmissably high current will flow

10. A multirange instrument (ammeter or voltmeter) has

  • multiple shunt or series  resistances inside the meter
  • variable coil turns
  • multi -coil arrangement
  • any of the above
