In any triangle abc r1r2+r2r3+r3r1
WebStudy with Quizlet and memorize flashcards containing terms like series If resistors are in series, Rtot = R1+R2+R3. If resistors are in parallel, Rtot = (R1R2R3)/((R1R2)+(R2R3)+(R3R1)) Based off of these two equations, for series, Rtot will always be larger than the largest individual resistance because it is the sum of all three …
