Voltmeter: meaning, definitions and examples
⚡
voltmeter
[ˈvoʊltˌmiːtər ]
Definition
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.
Interesting Facts
Etymology
- The term 'voltmeter' is a combination of 'volt,' named after Italian physicist Alessandro Volta, and 'meter,' a common suffix for measuring instruments.
- The word 'volt' itself was introduced in the early 19th century to honor the contributions of Volta to electricity.
- The naming of the voltmeter emerged in the late 1800s, during a period of significant advancements in electrical engineering.
Historical Context
- The first practical voltmeter was developed in the mid-19th century, reflecting the growing importance of electricity in technology and industry.
- Originally, the design of voltmeters was quite rudimentary, often utilizing simple galvanometers to indicate voltage levels.
- As electrical power systems grew, the demand for accurate and reliable voltage measurements led to innovations in voltmeter designs.
Science and Technology
- Voltmeter technology has evolved significantly, with modern devices incorporating digital displays and advanced sensors for precise readings.
- There are two main types of voltmeters: analog, which uses a needle, and digital, which shows numbers on a screen, making readings easier to understand.
- Some voltmeters can even log data over time to help analyze how voltage changes in a circuit.
