A digital voltmeter is an electronic instrument used to measure the electrical potential difference, or voltage, between two points in a circuit. Unlike analog voltmeters that use a moving needle to indicate the voltage level, a digital voltmeter displays the measured value as a precise numerical readout on a digital screen. Digital voltmeters are valued for their accuracy, ease of reading, and ability to provide quick results. They are commonly used in laboratories, industry, and by hobbyists to troubleshoot and test electrical and electronic equipment.
