parallellkobling og Gjeldende Divisjon

    • To elementene er parallelle hvis de er koblet mellom samme par notater. Hvis hvert element er parallelt med ethvert annet element er det som kalles en parallellkobling.

    • Den tilsvarende motstand motstand koblet i parallell er

      Den tilsvarende konduktans er summen av de enkelte ledningsevne
