I'm trying to create a function that will calculate any amount of resistors in parallel but I do not know how to allow an undetermined amount of arguements for input (rather than a fixed amount). Basically it would look like this pll(R1,R2,R3,Rn) where Rn would be anything from R2 to R1000 or whatever. The equation is 1/(1/R1 + 1/R2 + 1/R3 + 1/Rn).(adsbygoogle = window.adsbygoogle || []).push({});
