5. Circuit (7 points) A DC circuit with two batteries and two resistors is shown in the gure below. Battery 1 is 8 V, and battery 2 is 14 V. Resistor A has a resistance of 19 2, and resistor B has a resistance of 6 Q. "' Battery 2 Resistor A Resistor B Battery 1 _ + I (a) (3 points) What is the current owing in the circuit? Are the electrons that carry the current owing clockwise or counterclockwise around the circuit? (b) (2 points) A wire is added connecting the top and the bottom of the circuit, as shown below. What will be the current owing through this added wire? Be sure to indicate the direction of this current. Resistor A Battery 2 Resistor B Battery 1 Final Exam, page 5 of 5 (c) (2 points) Starting with the original circuit from part (a) above, how can a wire be added to cause a short circuit? Give your answer by drawing a diagram of the circuit with the added wire in your solutions. Explain why this additional wire shorts the circuit
