# If two resistors with respective resistance R1 and R2 are hooked up in parallel, the net resistance R is related to R1 and R2 by 1/R = 1/R1 + 1/R2. If the resistances are measured in ohms as R1 = 150Ω, R2 = 400Ω, both with a possible error of 10%, what is the net resistance and the maximum possible error in the calculated value of R?

Question

If two resistors with respective resistance R1 and R2 are hooked up in parallel, the net resistance R is related to R1 and R2 by 1/R = 1/R1 + 1/R2. If the resistances are measured in ohms as R1 = 150Ω, R2 = 400Ω, both with a possible error of 10%, what is the net resistance and the maximum possible error in the calculated value of R?
