A multimeter is mainly used to measure the three basic electrical characteristics of voltage, current, and resistance. It can also be used to test continuity between two points in an electrical circuit. ... Multimeters can be used for testing batteries, household wiring, electric motors, and power supplies.

What is the purpose of multimeter?

A digital multimeter is a test tool used to measure two or more electrical values—principally voltage (volts), current (amps) and resistance (ohms).

Why we use multimeter in our circuits?

A digital multimeter is an indispensable tool for testing, diagnosing, and troubleshooting electrical circuits, components, and devices. The first digital multimeter was introduced in the late 1970s, and has proven much more accurate and reliable than the old needle-based analog meters.
