Question

What does a voltmeter measure?

  1. Energy going in
  2. Energy going out
  3. Each coulomb passing through a component
  4. All of the above

hintHint:

All of the above

The correct answer is: All of the above


    • A voltmeter measures the energy going in, the energy going out and each coulomb of charge passing through a component.
    • So, the correct option is d.
