Nodspänningar
Nodspänningar, or node voltages, are the electrical potentials measured at the junctions of components within an electrical circuit. In the context of circuit analysis, the term refers to the set of voltages that determine the operating state of the network. By definition, the voltage at a node is set relative to a reference node, often called the ground. All other node voltages are expressed with respect to this reference.
The concept of nodspänningar underpins nodal analysis, a systematic method for solving linear electrical networks. The
A simple illustrative example is a two‑node circuit: a voltage source in series with a resistor connected
Nodspänningar are foundational in both analog and digital circuit design, providing the basis for simulation tools
