... Connect the two resistors in PARALLEL with the voltage source. Start incrementing the voltage by 2 volts until you reach 12 volts. For each voltage, measure the current in the circuit with the ammeter. Graph the voltage versus current. From the slope, calculate the total resistance of the circuit. F ...
