In the context of electrical and electronics engineering, a **node** refers to a point in a circuit where two or more circuit elements (like resistors, capacitors, inductors, or power sources) are connected together. It is essentially a junction or a meeting point for electrical components.
In simpler terms, a node is like an intersection in a network of electrical components, where the current can flow to or from multiple paths. Each node has a single voltage, and it is usually used when analyzing circuits with techniques like **Kirchhoff's Current Law (KCL)** or **Kirchhoff's Voltage Law (KVL)**.
For example, in a simple circuit, if two resistors are connected at the same point, that connecting point is a node.
