parallellforbindelse

Parallellforbindelse, also known as parallel connection, is an electrical circuit configuration where components are connected across common points. This means that the voltage across each component in a parallel circuit is the same. Current, however, divides among the branches of the parallel circuit. The total current entering the parallel section is the sum of the currents flowing through each individual component.

In a parallel circuit, if one component fails or is removed, the other components will continue to function because the circuit remains complete. This is a key characteristic that distinguishes it from a series connection, where a break in the circuit would cause all components to stop working. The equivalent resistance of a parallel circuit is always less than the smallest individual resistance. This is calculated using the formula 1/R_total = 1/R_1 + 1/R_2 + ... + 1/R_n.

Common examples of parallellforbindelse include household electrical wiring, where multiple appliances are connected to the same power source, and the internal wiring of many electronic devices. The ability for components to operate independently and receive the same voltage makes parallel connections highly versatile and practical for many applications.
