A voltmeter is a tool that measures the voltage between two points in an electric circuit. It is like a thermometer that measures the temperature of a liquid.
Voltmeters have two leads, one red and one black. The red lead is connected to the point with higher voltage, and the black lead is connected to the point with lower voltage.
The voltmeter has a scale that shows the voltage. The higher the voltage, the higher the reading on the scale.
Voltmeters are used to measure the voltage of batteries, power supplies, and electrical circuits. They are also used to measure the voltage of lightning strikes.
The technician used a voltmeter to measure the voltage of the battery.
