There are four points in this circuit where voltages are different. They can be referred to as nodes. Whenever we say "voltage" at a point, the reference point is ground of that circuit. Ground is also a node, which is considered to be at zero voltage. Here it would be the -ve terminal of the supply. So there are four nodes in this circuit. Node is the point at which there is a common connection in between two or more elements. I can say that one is between the inductor and the source, the second one between R and C, is there another one bewteen L and R.

Because at these points voltages are not same. Wherever there is difference in voltage between two points then it can be called as node. Sign up to join this community. If a branch is a path between two nodes or a circuit element, then a node is a point through a circuit element. A node is the point where two or more branches are connected together. Node is represented by a dot in an electric circuit. Understand that if a short circuit a plain conducting wire is connected to two nodes, these two nodes form a single node.

Observe the example circuit below:. In the circuit above we can list three nodes that exist inside it: nodes a , b , and c. The three nodes connected to a single wire form a single node b. Just as node b , we can also treat node c as the same. After understand a bit about node, we can redraw the circuit above into circuit below:.

In a short explanation, a loop is formed from a node passing through a set of nodes and returning to the starting point or node without passing the same node twice or more. We can call a loop independent if the loop contains at least one branch which is not a part of another independent loop.

A loop is a closed path inside an electric circuit. In the circuit above we list the independent loop:. After learning about branches, nodes, and loops we can draw some conclusions to close our study here.

Assume that we have a network consists of:. These three numbers will satisfy the basic theorem of network topology:. The equation below will help us greatly on studying voltage and current in an electric circuit.

The term node can be used to distinguish between series and parallel circuits. A series circuit is when two or more circuit elements share a single node and carry the same amount of current. A parallel circuit is when two or more circuit elements are connected to the same two nodes and carry the same voltage across them.
