10. Two flashlights are each powered with four batteries. All of the batteries are 1.5 volts. One of the flashlights has a bulb with a resistance of 6 ohms and the second flashlight has a bulb with a resistance of 4 ohms.

a. Draw circuit diagrams for each of the flashlights. Label the battery voltage and bulb resistance for each diagram.

b. Calculate the total voltage for each flashlight.

c. Using the total voltage and the bulb resistance, calculate the current for each flashlight.

d. Which flashlight will be brighter, the one with the 6-ohm bulb or the one with the 4-ohm bulb? Describe the reasoning.

11. Is a short circuit considered an open circuit, closed circuit, both, or neither? Describe the reasoning.

5. Describe what happens to the electrons when another battery is added to a circuit system. How would one describe the relationship between voltage and current? In other words, in a circuit, how does current change as voltage increases or decreases?
