1. The problem statement, all variables and given/known data I'm doing a lab report and the last question is, how would your measurements (currents and voltages across each resistor) be affected if the resistance of the wires is 0.01 Ω and the internal resistance of the voltmeter is 10 MΩ? 2. Relevant equations 3. The attempt at a solution I'm going to take a guess here. For the wire, do I just pretend there is a resistor of 0.01 Ω right next to one of the power supplies? Or do I have to add it in each of the three branches? For the voltmeter, do I add a 10 MΩ resistor in parallel to each of the three resistors, find their equivalent resistance and then use that for the Kirchhoff current equations? Thanks.
