I have a question regarding series circuits with 3 resistors. I have this circuit, and I do my normal testing for voltage, current, and resistance. Each one of the resistors is a 3kiloOhm resistor. Voltage is 12 v system. Schematic wise, I would have resistor 1 on the bottom leg, resistor 2 on the leg adjacent to the voltage source, and resistor 3 on the upper leg (adjacent from resistor 1). If resistor 2 voltage is halved, what would be the cause of this? Would it be resistor 1 open, resistor 1 short, resistor 2 short, or resistor 3 open? I have been wrecking my brain to try and understand this. If anyone could explain it to me, it would be very appreciative.
