Which is the closed path in a circuit?

Option 4 : Loop

A closed path made by several branches of the network is known as Loop.

Node:

A point or junction where two or more circuit’s elements (resistor, capacitor, inductor etc.) meet is called Node. In other words, a point of connection between two or more branches is known as a Node.

Branch:

That part or section of a circuit which locate between two junctions is called the branch. In a branch, one or more elements can be connected, and they have two terminals.

Loop:

A closed path in a circuit where more than two meshes can occur is known as 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
