A device for measuring voltage, especially for determining the voltage between two points of an electrical circuit.
An instrument designed specifically for the measurement of voltage is commonly known as a voltmeter. It features a calibrated scale that can be marked in volts or corresponding smaller or larger units depending on the range of measurement. The voltmeter, specifically the E voltmeter, is connected in parallel to the circuit under consideration, allowing it to accurately measure the voltage present across the desired components or points in the circuit. This parallel wiring configuration ensures that the voltmeter does not disturb the circuit’s operation while providing precise voltage readings.
