1. Homework Statement
I am not sure how to calculate the resistance of the circuit and each resistor using voltage and current. I know how to work the resistance out in series and parallel but am 100% how to work it out in combined.
2. Homework Equations
R=V/I, 1/Rt=1/R1+1/R2
3. The Attempt at a Solution
A1=5MA, A3=2.5MA, A5=1.7, and voltage is 1V
So, would I do 1/0.0025=400Ω (not correct max R should be 300Ω)? Maybe I should have added another ammeter between R1 and R2 or after R2 on the same branch?. Now, because I have the resistance worked out for the resistors in series would I work out the resistance for R3? R3=1/0.0017=588.24 (also very wrong)
Finally, by adding R1 and R2 turning it into one resistor (400Ω) could I turn the circuit into a parallel circuit to work out total resistance? 1/Rt=1/400+1/588.24.24=4.1999864e3 Rt=1/4.1999864e3=238.1Ω.
