For an electronics project you have three resistors R1, R2, and R3. Unfortunately, only R1 = 3Ω is labeled. Luckily, you paid attention in your physics lectures and you recall the mathematical relationships of (three) resistors in a series circuit and in a parallel circuit. When all three resistors are connected in parallel you measure the total resistance Rparallel = 4 3Ω, and you find a total resistance of Rseries = 13Ω when they are connected in series. a) First,...
