Rinnankytkettynä

Rinnankytkettynä is a Finnish term that translates to "connected in parallel" or "wired in parallel" in English. It describes a method of connecting electrical components such as resistors, capacitors, or batteries in a circuit. In a parallel connection, the components are joined across the same two points in the circuit, meaning that the voltage across each component is the same.

This configuration differs from a series connection, where components are connected end-to-end, forming a single path for the current. In a parallel circuit, the total current flowing into the junction splits among the branches, with each branch receiving a portion of the current. The total resistance in a parallel circuit is lower than the resistance of any individual branch. This property is often utilized to reduce overall resistance or to allow different components to operate independently with the same voltage supply. For example, household electrical outlets are wired in parallel, allowing multiple appliances to be powered simultaneously without significantly affecting each other's voltage. The term is fundamental in understanding basic electrical circuit design and analysis.
