Multiple choice questions in Measuring Devices

This is the Multiple Choice Questions (MCQs) in Chapter 3: Measuring Devices from the book Teach Yourself Electricity and Electronics, 5th edition by Stan Gibilisco. If you are looking for a reviewer in Electronics Engineering this will definitely help you before taking the Board Exam.

Start Practice Exam Test Questions

1. The force between two electrically charged objects is called:

  • A. Electromagnetic deflection.
  • B. Electrostatic force.
  • C. Magnetic force.
  • D. Electroscopic force.

  • A. Electromagnetic deflection.
  • B. Electrostatic force.
  • C. Magnetic force.
  • D. Electroscopic force.

3. Suppose a certain current in a galvanometer causes the needle to deflect 20 degrees, and then this current is doubled. The needle deflection:

  • A. Will decrease.
  • B. Will stay the same.
  • C. Will increase.
  • D. Will reverse direction.

4. One important advantage of an electrostatic meter is that:

  • A. It measures very small currents.
  • B. It will handle large currents.
  • C. It can detect ac voltages.
  • D. It draws a large current from the source.

5. A thermocouple:

  • B. The electromagnet meter need not be aligned with the earth’s magnetic field.
  • C. The permanent-magnet meter has a more sluggish coil.
  • D. The electromagnet meter is more rugged.

7. An ammeter shunt is useful because:

  • B. Is placed between the negative pole of the supply and the circuit working from the supply.
  • C. Is placed between the positive pole of the supply and the circuit working from the supply.
  • D. Is placed in parallel with the circuit that works from the supply.

10. Which of the following will not cause a major error in an ohmmeter reading?

  • A. A small voltage between points under test.
  • B. A slight change in switchable internal resistance.
  • C. A small change in the resistance to be measured.
  • D. A slight error in range switch selection.

11. The ohmmeter in Fig. 3-17 shows a reading of about:

  • C. Can withstand higher voltages safely.
  • D. Is sensitive to ac as well as to dc.

13. Which of the following is not a function of a fuse?

  • A. To be sure there is enough current available for an appliance to work right.
  • B. To make it impossible to use appliances that are too large for a given circuit.
  • C. To limit the amount of power that a circuit can deliver.
  • D. To make sure the current is within safe limits.

14. A utility meter’s motor speed works directly from:

  • A. The number of ampere hours being used at the time.
  • B. The number of watt hours being used at the time.
  • C. The number of watts being used at the time.
  • D. The number of kilowatt hours being used at the time.

15. A utility meter’s readout indicates:
