Nodes, Branches and Loops of a Circuit
An electric circuit based on three concepts, namely, node, branch and loop. As per definition, an electric network is a combination of interconnected circuit elements. A network may or may not provide closed path to the electric current to flow. But, an electrical circuit may be a combination of one or more networks which gives closed path to the electric current. That means, when one or more networks are interconnected together to complete one or more paths to the current, an electric circuit is formed.
An electric circuit does have three conceptual things as mentioned below.
Nodes of Electric CircuitThe point through which an circuit element is connected to the circuit is called node. It is better to say, node is a point where, terminal of two or more circuit elements are connected together.

NB:- If three is no element between two or more connected adjacent nodes, these nodes can be recombined as a single node.
Finally, the circuit can be redrawn as,
Branch of Electric CircuitThe elements connected to an electric circuit is generally two terminal element. When, one circuit element is connected to the circuit, it connects itself through both of its terminals, to be a part of a closed path.
Any of the circuit elements, when connected to the circuit, it is definitely connected between two nodes of the circuit.
Loops in Electric CircuitAn electric circuit has numbers of nodes. If one starts from one node and after going through a set of nodes returns to same starting node without crossing any of the intermediate node twice, he has travels through one loop of the circuit.
