Common traits of digital multimeters (DMMs). Classifying DMMs by their amount of digits. What role do digitizers play in making voltage measurements? Measuring voltage may be the most basic ...

This video talks about the techniques for measuring drain voltage and current. This course will show you how to accurately measure the MOSFET drain voltage and current with the Power Integrations’ ...

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, ...

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 ...

Neither a high resistance-grounded system nor an underground system can supply line-to-ground loads. If protection and monitoring equipment is connected from line to ground, then it must not threaten ...

Semiconductor junctions — from the millions of transistors used in ICs to the large-area compound junctions that make high-brightness LEDs possible — can all suffer early failure due to increased heat ...

Electricity is a key ingredient in living bodies. We know that voltage differences are important in biological systems; they drive the beating of the heart and allow neurons to communicate with one ...

Measuring resistance doesn’t seem to be a big deal. Put your meter leads across two wires or terminals and read the value, right? Most of the time that is good enough, but sometimes you need better ...
