### homework and exercises - Error calculation in parallel

Mar 30, 2015 · For the above problem, let R s denote series combination. Then R s = 300 ± 7 ohm. Let R p denote parallel combination. ∴ R p = R 1 R 2 R 1 + R 2 = R 1 R 2 R s. Ignoring errors, we get R p = 200 3 ohm = 66.67 ohm. % error in R 1 = 3, % error in R 2 = 2, % error in R s = 7 3. Hence, % error in R p …

When wanting to compare two values that are both determined by experimentation, we don't have a "correct" or accepted value to which to compare, so we simply look at how different the two values are as a percentage of their average value: ( 2 ) % difference =. |value 1 − value 2|. value 1 + value 2. 2.
