Question

Ma puteti ajuta va rog !!! Rp si Rs dau coroana !!

Answer 1

N-am prea inteles ce trebuie de aflat, da cred ca R in paralel in acele 2 cazuri si R in serie la amindoua:
[tex] \frac{1}{Rp1}= \frac{1}{R1}+ \frac{1}{R23} \\ \frac{1}{Rp1}= \frac{1}{R1}+ \frac{1}{R2}+ \frac{1}{R3}\\ \frac{1}{Rp1}= \frac{3}{R}\\ Rp1= \frac{R}{3}\\ Rp2= \frac{R}{2}\\ Rs=Rp1+Rp2\\ Rs= \frac{R}{3}+ \frac{R}{2}\\ Rs= \frac{2R+3R}{6}\\ Rs= \frac{5R}{6} [/tex]
