sarjakytkentään

Sarjakytkentään refers to a serial connection in Finnish. In electrical engineering, a serial connection, also known as a series circuit, is a circuit in which components are connected along a single path, so the same current flows through all of them. If one component in a serial connection fails, the entire circuit is broken, and current stops flowing. The total resistance in a serial connection is the sum of the individual resistances of each component. Voltage sources connected in series add their voltages, but the current remains the same through each component. This principle is fundamental to understanding electrical circuits and is applied in various applications, from simple battery packs to more complex electronic devices. For example, old-style Christmas tree lights were often wired in series, meaning if one bulb burned out, the entire string would go dark. Modern lighting often uses parallel connections to avoid this issue. Understanding sarjakytkentään is crucial for anyone studying or working with electricity.
