A multimeter and its test leads allow electrical workers to reach into an energized panel, touch live circuit components with the end of the test leads, and capture electrical readings like voltage, ...

Craig brought 15 years of automotive journalism experience to the Cars team. A lifelong resident of Michigan, he's as happy with a wrench or welding gun in hand as he is in front of the camera or ...

When a voltage is applied to a material or device,current will flow through it. How much current will flow is based on theresistance that the material applies to a circuit. The resistance of a ...

This multimeter add-on is called the Half Ohm. It allows you to measure small resistance values, and can be used to track down shorts on a PCB. The board acts as a pass-through for both probes. When ...

Digital multimeters (DMM), once called voltmeters, have been described as the tape measure for engineers in the new millennium. With electronics and electrical circuits included in almost every ...

Part of Design and Technology Electronic and microelectronic control systems Using Ohm’s Law (V=ꞮR), you can calculate the expected values for voltage, current, and resistance in a circuit. Ohm's law.

Modern digital multimeters (DMMs) are user-friendly, accurate, and safe — when used correctly! Reading voltage is simple, but measurements must be properly interpreted. With a clamp-on DMM, accurate ...
