Read more
A multimeter is a useful tool to have around because it can test a variety of electronic components. A multimeter can be a handy tool for homeowners to test batteries. Electricians can also use it to test wires.Â
America Tools, located in Miami, Florida, is a top supplier of tools for customers nationwide. We have various multimeters available from top tool manufacturers. Here, we explain how to use a multimeter.
What Is a Multimeter?
A multimeter is an electrical tester used to measure multiple electrical values. There are digital and analog multimeters, and they measure the following:
Current
Current is the amount of electricity flowing through a circuit and it is measured in amps. The number of amps flowing through a circuit is the difference between the voltage applied and the resistance present. A milliamp is 1/1,000 of an amp and is the most common unit of amps measured with a multimeter.
Resistance
Resistance is the opposition to the flow of current through a circuit. Essentially, it is the force that counteracts the flow of electricity. It is measured in ohms. Digital multimeters also test for continuity, which is the absence of resistance within a circuit.
Voltage
Multimeters can test two forms of voltage: alternating current (AC) and direct current (DC). AC is the voltage
