# How to determine the number of Nodes, Branches, Loops and Meshes in a Circuit?

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
Consider the following Simple Electric Circuit which contains on 7 components or elements
