RossWhen a light switch is turned on, electrical energy from the power source is converted into light energy and heat energy by the light bulb. The electrical energy flows through the circuit, causing the filament in the bulb to glow and emit light while also producing heat as a byproduct.

Why wont your energy efficient light bulb power completely off when the light switch is turned off?
Energy efficient light bulbs may have residual energy stored in them even when the light switch is turned off due to capacitors and other components. This residual energy allows them to power on more quickly when the switch is turned back on. It is normal and does not indicate a malfunction.
Do light sockets without bulbs in them still use energy when their switch is turned on?
No, light sockets without bulbs do not consume energy when the switch is turned on because there is no electrical load present to draw electricity. The circuit remains open when there is no bulb, so no electricity flows through it.
When a light switch is turned on what is done to the curcuit?
When a light switched is turned on the circuit is usually closed.
When the flashlight is turned on what energy changes?
When a flashlight is turned on, electrical energy from the battery is converted into light energy and heat energy by the bulb. The chemical energy stored in the battery is transformed into electrical energy, and then into light and heat energy by the bulb to produce the illumination.
What 3 kinds of energy are involved when a light bulb is turned on?
When a light bulb is turned on, electrical energy is converted into light energy and heat energy. Electrical energy powers the flow of electrons through the filament, generating light energy and heat energy in the process.
