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 ...

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 ...

Observations on nodal and loop analysis that can save a fair amount of scribbling of equations when using Kirchhoff's laws. In a previous Idea for Design, Anshi Chen outlined a method for analyzing ...

Based on a presentation to the 57th Southwestern Petroleum Short Course, Lubbock, Tex., Apr. 26-29, 2010. As shown with a nodal analysis, the use of wellhead chokes on electrical submersible-pumped ...
