When voltmeter is connected in series with resistance R1, it shows voltage U1 = 198 V, but turned on in series with R2 = R * R1, voltmeter shows U2 = 180 V. Find R1 and voltage in the network if voltmeter inner resistance r = 900 Ω.
5. Find the total resistance of this circuit: R2-200Ω R1 100Ω R3-300Ω
Two identical resistors, R1 and R2, are
connected in parallel, and this parallel combination is then
connected in series with a 100 Ω resistor, R3 as shown

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,...
