Homework Equations
Resistors in series and parallel formulas.
The attempt at a solution
Very confused with part (b)!
So in the first square or w/e you call it (left side), R1 in series with R1 so that's 20Ω + 20Ω = 40Ω. Then the second square (middle), R2 in series with R1 so 10Ω + 20Ω = 30Ω. then 40 and 30 are in parallel 40-1 + 30-1 = 7/120-1 = 17.14Ω.
But my solution Manuel has 32Ω as the resistor equivalent. I know I am making a mistake somewhere but i don't know what my mistake is.
help please!
