This article describes how to measure MOSFET drain voltage and current. As part of that discussion it outlines how to use several types of current probes, how to identify the correct measurement ...

The first one (the primary circuit) is the wire in which the current flows. The second one (the secondary circuit) is inside the meter. The secondary circuit consists of a much higher number of coil ...

Measuring current and voltage You need to know how to measure the current that flows through a component in a circuit and the voltage across it.

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 ...
