Solving and analyzing electrical circuits and networks, you must know about Nodes, Branches, Loops and Meshes. So we are here with a simple tutorial ever to find all these terms in electric circuits.

**Node**

A point or junction where two or more circuit’s elements (resistor, capacitor, inductor etc) meet is called Node

**Branch**

That part or section of circuit which locate between two junctions is called branch

In branch, one or more elements can be connected and they have two terminals.

**Loop**

A closed path in circuit where more than two meshes can be occurred is called loop i.e. there may be many meshes in a loop, but a mesh does not contain on one loop.

**Mesh**

A closed loop which contains no other loop within it or a path which does not contain on other paths is called Mesh.

**Let’s make it easier.**

Now will find all these terms one by one with the following simple steps

Nodes = Branches – 1 i.e.<br />N = B-1

Or B = N + 1<br />Branches = Nodes + 1

Branch

That the terms junction or point mean one and the same must be emphasized.
