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
