For the circuit above the x's represent the wire and R represents the resistance. o's just fill in open space - ignore them. Find the equivalent resistance between points A and B.
R1=5 ohms
R2=4 ohms
R3=6 ohms
R4=10 ohms
R5=8 ohms
R6=7 ohms
R7=3 ohms
So i need to find the total resistance in the circuit. I know that R4,5, and 6 are in parallel so their resistance should add up like 1/(1/10+1/8+1/7) to give 2.72 ohms. so the rest of the resistances are in series so you just add them all up right? when i add them all together with 2.72 ohms, I am not getting the right answer. What am i doing wrong? please help. thanks.
