This post answers the question "What is mesh and node analysis". This two techniques are both used as…
Volt-ampere characteristics of a circuit part with source
Ohm’s Law can be applied to a piece of a circuit with a source, and we can draw…
Kirchhoff’s Law application for circuits analysis
Basic laws of electric circuit theory are Kirchhoff's Laws – the law of the currents balanced in the…
Kirchhoff’s Law – mesh method
The idea of this mesh method is calculating mesh currents of meshes (closed loops in a circuit), instead…
Kirchhoff’s Law – nodal method
The idea of this nodal method is to find voltages of the nodes using the first Law of…
Superposition principle
In the linear circuit with voltage sources, mesh currents are linear functions of mesh EMFs. Ii=1∆R∑k=1nVk∆ki The current…
General nodal analysis
It is possible to generalise the Nodal analysis method to use it for all electric circuits. This means…
Links and Loop analysis
Let us consider the circuit analysis method, using a tree structure. For example, we take a tree of…
