![]() ![]() The loop has two nodes: positive and negative.Ī series circuit still has one loop or path, and more than two nodes (i.e., one between each pair of components).Ī parallel circuit has only two nodes and all components are between those two nodes.Ī compound circuit has more than one path and more than two nodes. NODES AND LOOPSĪ simple circuit has one loop called the “path”, which is the circuit. If you’re a beginner, as your skillset develops, it is recommended that you move on from using VIRP tables. VIRP (i.e., EIRP) tables are useful for beginners as they force you to think of all options, and develop good practices for series and parallel circuits.Ĭompound circuits can be solved with VIRP tables, requiring a little more thought about whether two (or more) components are actually in series or parallel. To recap from last month and other previous issues of DIYODE Magazine, common tools for circuit analysis are Ohm’s Law, Kirchhoff’s Laws (KVL and KCL) and the Power Formulae. While compound circuits will be the aim of the exercise, we will also look at techniques for the easiest of the complex circuits, as well as give you something to work on. Of course we will be taking the least bumpy ride we can manage without making it completely Sesame Street! This issue we continue attempting to fill your circuit analysis toolbox with methods used by electricians, electronics and electrical engineers. Sometimes the best way to find an unknown, is to attack the unknown with a black box. ![]()
