Sarjaankytketyissä

Sarjaankytketyissä is a Finnish term that translates to "in series connection" or "serially connected" in English. It refers to a configuration where electrical components are connected end-to-end, forming a single path for the electric current to flow. This means that the current flowing through each component in the series is the same.

In a series circuit, the total resistance is the sum of the individual resistances of each component. If one component in a series circuit fails or is removed, the entire circuit is broken, and the current stops flowing. This is a key characteristic of series connections. Applications of series connections include simple circuits like Christmas lights (though modern ones often use parallel elements for better fault tolerance), switches in safety systems, and some types of sensors.

The voltage across each component in a series circuit is proportional to its resistance. The sum of the voltage drops across each component equals the total voltage supplied by the source. This principle is described by Kirchhoff's voltage law. Understanding series connections is fundamental to electrical engineering and helps in designing and troubleshooting electrical systems.
