## Circuit fundamentals: Methods of analysis nodal / mesh

When designing a complex electrical device there are a lot of factors that occur, like current leaks, heat flow, electromagnetic fields, behaviour of electrical…

## Circuit fundamentals: 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 a Volt-Ampere characteristic for this piece…

## Circuit fundamentals: 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 circuit nodes (first Kirchhof's Law) and…

## Circuit fundamentals: Kirchhoff’s Law – mesh method

The idea of this mesh method is calculating mesh currents of meshes (closed loops in a circuit), instead of the currents of branches, using…

## Circuit fundamentals: Kirchhoff’s Law – nodal method

The idea of this nodal method is to find voltages of the nodes using the first Law of Kirchhoff, concerning the reference (ground) node.…

## Circuit fundamentals: 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 in any mesh, containing more then…

## Circuit fundamentals: General nodal analysis

It is possible to generalise the Nodal analysis method to use it for all electric circuits. This means the nodal method should work with…

## Circuit fundamentals: Links and Loop analysis

Let us consider the Link Loop analysis method, using a tree structure. For example, we take a tree of the graph and arbitrary link.…

## Circuit fundamentals: Equivalent voltage and current sources

Equivalent voltage and current sources are equivalent - if you are replacing one with another the rest of the circuit response is the same.…
