Describing voltage and current relationships in electric circuits are often precisely analogous with the resultant equations when dealing with mathematical behavior of fluid-flow and heat-flow systems ...

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 a previous Idea for Design, Anshi Chen outlined a method for analyzing electrical circuits using Kirchhoff’s current law (KCL) in a novel way that allowed designers to simply write down the needed ...

It is hard to get very far into electronics without knowing Ohm’s law. Named after [Georg Ohm] it describes current and voltage relationships in linear circuits. However, there are two laws that are ...
