Basic physics, my weakness..
1. What is the significance of the voltmeter reading 0? Does this mean that there is no current flowing through?
2. Why is it that when the voltmeter reads 0, we should know that the voltages through R and R1 are equal?
3. And does this imply that if the voltmeter did NOT read 0, then the voltages through R and R1 would NOT be equal?
4. I assume that the IR3 = I1R2 because the same current flows through those two resistors?
