Researchers have developed a way to assess soil health by measuring the electric current produced by its tiniest microbes. They used a probe originally developed to measure the electrochemical signal ...

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 ...

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 ...

Leakage current is one of the most stringent, yet telling, parameters of possible danger to patients or caregivers. It does not take much electric current flowing through the human body to cause harm.
