This Design Idea shows how tocalculate the inductance of amultilayer air-core coil using only itsdimensions and resistance. If you knowthe dimensions and the number of turnson an air-core coil, you ...

As Lenz’s Law states, an inductor in a circuit opposes the flow of current through it because the flow induces an electromotive force (emf) that opposes it. In order to keep the current flowing ...

A typical Twin Feeder cable, or more popularly referred to as "Zip Cord", consists of two adjacent conductors separated by insulation, or commonly referred to a "dielectric". For convention we assume ...

We like to pretend that our circuits are as perfect as our schematics. But in truth, PCB traces have unwanted resistance, capacitance, and inductance. On the other hand, that means you can use those ...
