Measuring dynamic currents with an oscilloscope is challenging, but this updated differential current probe makes it simple ...

Feedback refers to a core concept in circuit design and control theory, used to stabilize amplifiers and control system ...

Why get up close and personal with a resistor when you can tweak it from a distance? Remote variable resistors make analog circuit control easier, neater, and a lot more fun. Well, we are about to ...

If you need a potentiometer for a project, chances are pretty good that you’re not going to pick up a pencil and draw one. Then again, if you’re teaching someone how a variable resistor works, that ...

Abstract: In some conditions, the flux in the core of current transformers (CT) increases. If this increase in flux leads to saturation of the protective core, it can create a lot of problems in power ...

What kinds of applications utilize precision resistor trimming? Obvious applications include setting operational-amplifier gain and offset and voltage regulator output (Fig. 1a and 1b). But there are ...

A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider used for measuring electric potential, or voltage. If only two terminals are ...

One of the primary issues slowing the adoption of electric vehicles is the fear of being stranded with a dead battery and no charging stations nearby. In addition to the Biden Administration’s recent ...
