Live use of voltmeter

A voltmeter is also known as the voltage meter. It is an instrument that measures the voltage or potential difference in voltage known as the voltmeter. As we know, The voltmeter is always connected in parallel with the circuit. Some voltmeter is intended for the direct current called as a DC circuit and other designed for alternating current called the AC circuit.

Following precautions are taken:


  • Select the highest range voltage of the meter when the value of the voltage being measured is unknown.
  • The voltage of the circuit can be measured without breaking the circuit.
  • The test probe should be suitable to withstand against voltage tinder measurement.
