Paralellikytkennässä

Paralellikytkennässä, known in English as parallel connection, is an electrical wiring method where components are connected across the same two points in a circuit. This means that the voltage across each component in a parallel circuit is the same. Current, however, will divide among the parallel branches. The total current flowing into the parallel combination is the sum of the currents flowing through each individual branch.

This arrangement has several key characteristics. Firstly, if one component in a parallel circuit fails or is removed, the other components will continue to function because the circuit remains complete for them. Secondly, adding more components in parallel increases the total current drawn from the source, assuming the voltage remains constant. This is because the total resistance of the parallel combination decreases as more branches are added. The reciprocal of the total resistance is equal to the sum of the reciprocals of the individual resistances.

Paralellikytkennässä is commonly used in household wiring, where lights and appliances are connected in parallel to the main power supply. This ensures that each device receives the full mains voltage and can be operated independently of others. In other applications, it is used to increase the current-carrying capacity of a circuit or to provide redundancy. For instance, multiple batteries might be connected in parallel to supply a higher total current. Understanding paralellikytkennässä is fundamental to analyzing and designing electrical circuits.
