Solution

  1. A voltmeter is a device that measures the difference in electrical potential between two locations in an electric circuit.
  2. Voltmeters are used to measure voltages in both direct and alternating currents.
  3. A voltmeter's scale is measured in millivolts, volts, or kilovolts.
  4. Analog voltmeters move a pointer around a scale in proportion to the circuit's voltage; digital voltmeters utilize an analog to digital converter to show voltage numerically.
