Voltmeter: meaning, definitions and examples
⚡
voltmeter
[ ˈvoʊltˌmiːtər ]
measuring device
A voltmeter is an instrument used for measuring the potential difference, or voltage, between two points in an electric circuit. It is typically connected in parallel with the component whose voltage is to be measured. The voltmeter provides a reading on a scale, often in volts. Voltmeter designs can vary, with analog and digital versions available, providing varying levels of precision and ease of use. Understanding how to correctly use a voltmeter is fundamental in electronic testing and repairs.
Synonyms
electric potential meter, voltage meter
Examples of usage
- I used the voltmeter to check the battery voltage.
- The technician measured the voltage drop across the resistor with the voltmeter.
- You can test the output voltage of the power supply using a voltmeter.
- Always turn off the circuit before connecting the voltmeter.

Etymology
The term 'voltmeter' finds its roots in the name of Italian scientist Alessandro Volta, who is credited with the invention of the first chemical battery, known as the voltaic pile, in the year 1800. The word combines his surname, Volta, with 'meter', a suffix derived from the Greek 'metron', meaning measure. As electrical engineering evolved in the 19th century, the need to measure electric potential became increasingly important, leading to the creation of various measuring devices, including the voltmeter. The voltmeter has since developed through different technologies, from early analog designs using moving coils and galvanometers to sophisticated digital voltmeters that provide more accurate readings and additional functionality.
