Back in the early days of electricity, lab workers could measure electric current in a circuit using an ammeter (galvanometer) and voltage using a voltmeter. From there, they could calculate ...

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 ...

Home improvement addicts really get excited about their power tools. And in the shadow of drills and sanders, the multimeter doesn't get much love. Too bad, because multimeters are just as useful and ...

Measurement triangle: this quantum metrology triangle shows the relations between the three electrical units volt, ohm and ampere and the involved fundamental constants. Researchers at PTB are ...
