What is the unit of volt meter?
2 Answers
The unit of a voltmeter is the volt, which is represented by the symbol "V." A voltmeter is an instrument used to measure the electrical potential difference, or voltage, between two points in an electrical circuit.
To break it down a bit:
- **Volt**: The volt is the unit of electric potential difference in the International System of Units (SI). It is defined as the difference in electric potential that would drive one ampere of current through a resistance of one ohm. In other words, 1 volt = 1 joule per coulomb (1 V = 1 J/C).
- **Voltmeters**: These devices are designed to measure voltage. When you connect a voltmeter across two points in a circuit, it measures the electric potential difference between those points. The voltmeter is usually connected in parallel with the component or section of the circuit where you want to measure the voltage.
In summary, a voltmeter measures voltage, and its readings are expressed in volts.
