Rseries=Rtotal =R1+R2+...+RN
Rparallel=(Rtotal)-1=(R1)-1+(R2)-1+...
The Attempt at a Solution
So for my attempt, my assumption was that:
- The 18 and 12 Ω resistors were in series, so I combined them.
- I assumed the 20 Ω resistor at the top was in parallel with the 60Ω resistor under it and combined that.
- Then, the equivalent resistance of the 20 and 60 Ω resistors was in series with the 40 Ω resistor.
