This happens when you add more batteries to a series circuit.
What is a) longer battery life b) dimmer light c) brighter light d) no change in brightness?
A flashlight is covered entirely with aluminum foil and the light bulb doesn't go out when the switch is turned off because.
What is a) the aluminum foil is acting as an insulator and creating a short circuit b) the connections between the battery and the light bulb are open c) the battery has been used by too many classes and is dead d) the aluminum foil is completing the circuit to the bulb?
