Makers, developers, and hobbyists looking for a way to measure both voltage and current simultaneously may be interested in a new Arduino project published on the official Arduino blog. This project ...

Current sensing is used to perform two essential circuit functions. First, it is used to measure “how much” current is flowing in a circuit, which may be used to make decisions about turning off ...

The easy way to measure high AC currents is to use a clamp meter but these are generally quite expensive and cost several hundred dollars at a minimum. Add-on clampmeter adaptors can work well but ...

A decent current measurement sensor ought to be an essential part of every hacker’s workbench. One that is capable of measuring DC, as well as low and high frequencies with reasonable accuracy. And ...

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, ...

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 ...

This application note presents the application of leaded resistors in energy meters. It describes the different types of meters, and the typical usage of leaded resistors in energy meters. This ...
