In electrical engineering, a node is a point of connection between two or more branches in a circuit. It is the junction where two or more circuit elements are connected together. A node can be indicated by a dot or a bullet in a circuit diagram. It is important to note that a node consists of the entire section of wire between elements, not just a single point. This means that all points on the node have the same voltage, as per Ohms law).
In summary, a node in a circuit is a crucial concept that represents the junction of two or more branches, and it plays a significant role in understanding the behavior and analysis of electrical circuits.
