Where does the electricity go in a light bulb?
Electricity flows through the filament of a light bulb, heating it up and causing it to emit light. The electricity powers the light bulb, allowing it to produce illumination.
Is a light bulb an energy source?
No, a light bulb is not an energy source. It converts electrical energy into light energy. The energy source for a light bulb is the electricity that powers it.
Why does a battery power a light bulb?
A battery powers a light bulb by converting stored chemical energy into electrical energy. When the battery is connected to the light bulb, a circuit is completed, allowing the flow of electrons through the filament of the bulb, which produces light and heat.
What kind of energy makes the light bulb light up?
Electricity is the energy source that powers a light bulb and makes it light up. When electricity flows through the filament in a light bulb, it generates heat and light, resulting in illumination.
