Oh wow the formula in D H's post is really useful. Thank you so much for pointing that out. :biggrin: From inspection, that would imply that if you took a measurement a large number of times and measurement uncertainty is constant like in that previous example, the error would be quite small...

Homework Statement This isn't a specific problem. It's more of something that I have encountered before and I have been unable to find an answer to by looking online or through notes. Hopefully this thread might serve others with similar problems in the future. Say for example, you want to...

Hi. Thanks for the reply. Doing the following suggests that the uncertainty is ~139Ω. Looking online, I found a formula that corresponds to this answer. http://physics.stackexchange.com/questions/111507/relative-error-of-equivalent-resistance-of-resistors-in-parallel I would therefore have to...

Homework Statement We are told that resistor 1 has a resistance of 4700Ω ± 5% and resistor 2 has a resistance of 6800Ω ± 5% and the equivalent series and parallel resistances are to be calculated with an estimate of uncertainty. Homework Equations RSeries = R1 + R2 RParallel = R1 × R2 / R1 +...
