i seriously can't figure this problem out Due tomorrow i just want to create an excel program to calculate the voltages and currents at every resistor. can you at least tell me what is in parallel or in series or how to at least start it? I haven't even finished one circuits class and am a mechanical engineer. Circuits class was prerequisite for this course, but i waivered it. So i have no idea where to start. Our Teacher's Assistant drew the second diagram and said those circles were potentiometers. He said to look at the circuit in that way to make it easier.
