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 … WebDec 15, 2024 · 1 Answer P dilip_k Dec 15, 2024 Given that r1,r2,r3 are radii of ex-circles . we have the following relations r1 = Δ s −a,r2 = Δ s − b,r3 = Δ s − c where Δ is the area of the triangle ABC having lengths of the sides a,b,c and 2s = a + b + c Also given r1 = 2r2 = 3r3 So r1 r2 = 2 ⇒ s − b s −a = 2 ⇒ s −b = 2s − 2a ⇒ s +b −2a = 0 ⇒ 2s + 2b −4a = 0 ireland a terrible beauty jill uris
