Author’s note: This article shows how to derive circuit gain equations via a signal flow graph. With practice you may be able to write a gain equation by locating signal paths and loops in the ...

In addition, since all waveforms are constant-valued at equilibrium points, and so capacitors act as open circuits and inductors act as short circuits. There in lies the basic algorithm for computing ...

What do series and parallel circuits have to do with Christmas lights? In this episode of Crash Course Physics, Shini walks us through the differences between series and parallel circuits and how that ...

The well-known Kirchhoff’s current law is often used in linear circuit analysis. It’s also called Kirchhoff ’s first law, Kirchhoff ’s point rule, Kirchhoff ’s junction rule, and Kirchhoff ’s first ...
