Explain how light bulbs create light.(1 point)
Electricity flows through a conductor that transfers the energy to the light bulb and the
light bulb converts it to heat and light.
Electricity flows through a conductor that absorbs heat and turns the heat into light
energy.
Electricity flows through an insulator that absorbs electrical energy, transfers it to the
light bulb, and converts it to heat and light.
Electricity flows through a voltage that converts electrical energy into light
The correct answer is:
Electricity flows through a conductor that transfers the energy to the light bulb and the light bulb converts it to heat and light.
Electricity flows through a conductor that transfers the energy to the light bulb and the light bulb converts it to heat and light.
The correct answer is: "Electricity flows through a conductor that transfers the energy to the light bulb and the light bulb converts it to heat and light."
To understand how light bulbs create light, we need to look at the basic components of a light bulb.
A light bulb consists of a filament, which is typically made of tungsten, enclosed in a glass bulb filled with a gas such as argon or nitrogen.
When electricity flows through a conductor, such as a wire connected to the light bulb, it transfers energy to the filament.
The filament in the light bulb has a high resistance to the flow of electricity. As electricity passes through the filament, it encounters resistance, and this resistance causes the filament to heat up to a high temperature.
As the filament heats up, it starts to emit light. This is because of a process called incandescence. Incandescence is a phenomenon where a substance emits light when heated to a high temperature.
The high temperature causes the filament in the light bulb to glow, producing visible light. The gas inside the bulb helps to maintain the filament's high temperature without it burning out quickly.
So, to summarize, when electricity flows through a conductor in a light bulb, it transfers energy to the filament, which becomes hot and emits light through incandescence.
