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, ...

If you want to measure resistance and you know Ohm’s law, it seems like you have an easy answer, right? Feed a known current through the thing you want to measure and read the voltage required. A ...

Welcome back to our Tech Tip series! Today, we’ll review one of the most essential tools in every toolbox, a multimeter.

David Grant of ACT Meters provides a basic understanding of digital multimeters and how to use them to test alarm systems. He pays particular attention to safety The purpose of a multimeter is to ...

Stepper motors contain coil windings that require resistance measurements. Measuring resistance in a production environment often requires some special circuits that minimize errors. Resistance is ...

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 ...
