So this Monday I will have a test, and I know for a fact that one of the free response questions will be a circuit with a combination of series and parallel resistors.So my question is can you guys give me some tips on how to do these successfully. I know that I need to start from the farthest resistor. In parallel the voltage is the same, and throughout the circuit the voltage is the same for the series ones. Any more things I need to now? also I don't understand really when there are 2 batteries in the circuit.
