What is the use of digital multimeter?

A digital multimeter is a test tool used to measure two or more electrical values—principally voltage (volts), current (amps) and resistance (ohms). It is a standard diagnostic tool for technicians in the electrical/electronic industries.

Can a VOM measure AC current?

Both AC and DC currents can be measured with a multimeter by connecting the meter in series with the circuit, in which the current is measured provided the current in that circuit is limited or controlled by a load or appropriate values of resistance.

How do multimeters work?

Multimeters measure resistance by injecting a small current into the circuit, and then measuring the voltage drop across those points in the circuit. The known current, and the resulting voltage drop are then used to calculate the resistance using Ohm’s Law, V=I^2*R. Then probe the desired area of the circuit.

What are the three main function of the multimeter?

A multimeter is a measuring instrument that can measure multiple electrical properties. A typical multimeter can measure voltage, resistance, and current, in which case it is also known as a volt-ohm-milliammeter (VOM), as the unit is equipped with voltmeter, ammeter, and ohmmeter functionality.
