The atoms inside the wire of the lightbulb all have electrons which are pushed from atom to atom when the light is turned on, this is the current. When the electrons are pushed around the circuit they generate lots of heat because the wire in the bulb is so thin, this makes the wire glow white hot which creates the light.

What is the function of the metal casing and tip of the bulb?
metal casing and tip of the bulb are connected to the circuit which allows electricity to flow through the wires and light up the bulb
What happens when a light bulb burns out?
When a light bulb burns out it no longer makes light. This is because there is no way to connect the flow of electricity.
What makes a light bulb light up?
When an incandescent light bulb (the normal round ones that Thomas Edison invented) is placed into a "hot" circuit, (meaning there is electricity flowing through it), the electricity passes through the filament (little metal wires) on the inside. As the electricity passes through it, the wires heat up and make a chemical reaction causing light to be emitted.
Which material will allow electricity to flow between the battery and the the light bulb?
a copper wire
What happens if you unscrew a light bulb in a series circuit?
The circuit will have the flow of electricity interrupted.
Does electricity flow through a light when the light is turned off?
The OFF position on the light switch interrupts the flow of electricity to the light bulb. If the switch is ON, there is always electricity at the light socket, even when the light bulb is removed. if the lamp is still pluged in electricity is still flowing through the lamp even if it is off or on

Why are lights off when the switch is open?
Lights are on when a circuit (a path for electricity to flow through) is complete, and light is produced when electricity passes through the bulb because the material is energized by electricity, causing it to give off electromagnetic radiation. Most of the EM radiation is in the form of visible light, but some is in infrared which is why light bulbs (especially incandescent) get hot. When you turn off a switch, the circuit is broken at the switch, so electricity does not flow through the bulb.
How does electricity flow through a light?
A voltage is applied across the terminals of the light fixture to which the bulb is attached by two terminals, hot and neutral. A current then flows through the bulb. In an incandescent light the filament wire heats up and glows.
Is light the same as electricity?
Electricity is not the same as electric light. Electricity is the flow of electrons from one atom to the next. As electrons travel through the filament of a light bulb the resistance of the filament opposes the flow of current, which creates heat. The filament will heat up so much that it produces a visible light.

What causes incandescent light bulbs to produce light?
The filament in the bulb has a high resistance to the flow of electricity. As electricity passes through it, the filament heats up and begins to glow, giving off the visible light you see.
Which material will allow electricity to flow between the the battery and the light bulb?
a copper wire

How does a electric current flow through a light bulb?
The electrical current comes into the bulb from the metal side,flow through the filament ,and out the tip.
