2 131E 1 4 7. How much voltage is needed to produce a current of 6.0 A through a 24 V resistor? A. 4 V B. 18 V C. 30 V D. 144 V D because when you use the formula which is V-IR and you plug in the variables. V (6)(24) V = 144V and work is on paper. %3D 8. A short copper rod has a neutral charge. Negative charges are then applied to the right end of the rod. Which of the following describes the charge on the copper rod 5 s later? A. Both ends of the rod have a positive charge. B. The negative charge is spread evenly along the rod. C. Only the right end of the rod has a negative charge. D. All of the positive charge is in the middle of the rod. 9. A simple circuit is made using a battery, a light bulb, and some wire. Based on Ohm's law, which of the following should always decrease the brightness of the light bulb? A. using less wire in the circuit C. adding a second bulb in parallel B. adding a second bulb in series D. using a battery with a greater voltage Σ
