Jan 11, 2019 · A recent question asks students to calculate the total resistance of parallel resistors R 1 and R 2 with uncertainty. R 1 = 120 Ω (+/-10%). R 2 = 500 Ω (+/-10%). We would normally use the …

What are the different approaches to determine the equivalent resistance of nontrivial resistor networks in general, that cannot be reduced by the usual series and parallel rules? (The diagram belo...

Mar 30, 2015 · This is the question: There are two resistors with resistance values $R_1=100\pm3$ ohm and $R_2=200\pm4$ ohm. Find the equivalent resistance of parallel combination.

Aug 21, 2023 · It asks me to 'calculate effective resistance between P and Q'. I had a few attemps in trying to get the right answer (2R) by doing things like R + R + R (1/ (1/4 + 1/3 + 1/6)) and a few other …

Apr 27, 2019 · For example, if I have three parallel pipes. Resistance of whole system and three pipes are R, R1, R2, R3 respectively Pressure drop of whole system and two ends of three pipes are ∆P, …
