Spänningsserie

Spänningsserie, often translated as "tension series" or "voltage series" in English, is a concept used in the study of electrical engineering and electronics. It refers to a sequence or arrangement of electrical components, such as resistors, capacitors, or inductors, where the voltage across each component is related in a specific way. This relationship is typically governed by Kirchhoff's voltage law, which states that the sum of the voltage drops across all components in a closed loop is equal to the total voltage supplied to the loop.

In a simple spänningsserie circuit, components are connected end-to-end, forming a single path for current to flow. As current passes through each component, a voltage drop occurs across it, proportional to the component's resistance and the current flowing through it, or determined by its impedance in the case of AC circuits. The sum of these individual voltage drops will equal the source voltage. This principle is fundamental to understanding how voltage is distributed within a circuit and is crucial for analyzing and designing electrical systems. Applications range from simple voltage dividers to more complex power supply circuits.
