Energy: Forms, Transformation, Transfer, and Conservation
Item NG053003: Energy is transferred electrically from a battery to a light bulb in a flashlight only when the flashlight is switched on because energy can be transferred electrically only when there is a complete circuit.
A student places a battery into a flashlight. When the student switches the flashlight on, a complete circuit is made, and the light bulb lights up. When the student switches the flashlight off, the circuit is no longer complete, and the light bulb goes out. Is energy being transferred electrically from the battery to the light bulb in the flashlight? Why or why not?
- No, because energy cannot be transferred electrically from one place to another
- No, because even though energy can be transferred electrically, it cannot be transferred from a battery
- Yes, but only when the flashlight is switched on because energy can be transferred electrically only when there is a complete circuit
- Yes, as long as the battery is in the flashlight because electrical sources, such as batteries, transfer energy to electrical devices, such as flashlights, all the time
