Energy: Forms, Transformation, Transfer, and Conservation
Energy can be transferred from one system to another (or from a system to its environment) in different ways: by…
Item NG054002: Energy is transferred electrically from a power plant to a light bulb in a lamp only when the lamp is turned on because energy can be transferred electrically only when there is a complete circuit.
A student plugs a lamp into an electrical outlet in her house. When she turns on the light, a complete circuit is made, and the light bulb in the lamp lights up. Is energy being transferred electrically from the power plant to the light bulb in the lamp? Why or why not?
- No, energy is not transferred electrically to the light bulb from the power plant because energy cannot be transferred over long distances
- No, energy is not transferred electrically to the light bulb from the power plant. The electrical outlet created the energy that the lamp is using
- Yes, but only when the lamp is turned on because energy can be transferred electrically to the light bulb only when there is a complete circuit
- Yes, as long as the lamp is plugged in because some energy will be transferred to the light bulb even when the lamp is turned off and the circuit is not complete
