What device combines the functions of measuring voltage, current, and resistance into a single instrument, widely used by electricians and technicians?

Explanation

A multimeter is a versatile electronic testing instrument that combines the functions of a voltmeter, ammeter, and ohmmeter into a single device, allowing a user to measure voltage, current, and resistance, among other electrical properties, without needing several separate instruments. Multimeters are widely used by electricians, engineers, and hobbyists to diagnose electrical circuits and troubleshoot problems in household wiring, electronics, and automotive systems. Modern multimeters commonly feature a digital display, though older analog versions with a moving needle are also still in some use. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
