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 else can I help you with?
Why do you need electricity to light a light bulb?
Electricity is needed to light a light bulb because the flow of electrons through the filament inside the bulb generates heat and light energy. This energy causes the filament to emit light, thus illuminating the bulb. Without electricity, there is no source of energy to power the light bulb.
What happens when you turn off the light what happened to the electricity?
When you turn off a light, you are breaking the circuit that allows electricity to flow through the light bulb, causing the light bulb to turn off. The electricity in the circuit is still present and will continue to flow until the power source is disconnected or turned off.
How does a simple circuit with a light bulb work?
A simple circuit with a light bulb works by allowing electricity to flow from a power source, through a wire, and into the light bulb. The electricity energizes the filament inside the bulb, causing it to heat up and produce light. The circuit is completed when the electricity flows back to the power source through another wire.
What should be done to light a bulb?
To light a bulb, you need to connect it to a power source such as a battery or electricity supply. The electricity will flow through the bulb's filament, creating light energy and causing the bulb to illuminate. Make sure the connections are secure and the bulb is functioning properly.
What does the switch do in a torch?
The switch in a torch controls the flow of electricity to the light bulb. When the switch is turned on, it completes the circuit and allows the electricity to pass through, lighting up the bulb. Turning the switch off breaks the circuit, stopping the flow of electricity and turning off the light.
Can a bulb light if electricity doesn't get to the bulb?
No, a light bulb will not light up if electricity does not reach it. Electricity is required to flow through the filament in the bulb to generate light. If there is no electrical current, the bulb will not illuminate.
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

Will the bulb light if the filament is broken Why?
No, the bulb will not light if the filament is broken because the filament is the part of the bulb that creates light when electricity passes through it. Without a functioning filament, there is no source of light in the bulb.
What does static electricity have that causes a light bulb to light up?
Static electricity involves an accumulation of electric charge on the surface of objects, typically due to friction. When a static charge is discharged, it can create a flow of electrons. If this flow occurs through a light bulb's filament, it heats up and produces light. Thus, the movement of electric charge associated with static electricity is what can cause a light bulb to light up momentarily.
What does the switch do in a torch?
The switch in a torch controls the flow of electricity to the light bulb. When the switch is turned on, it completes the circuit and allows the electricity to pass through, lighting up the bulb. Turning the switch off breaks the circuit, stopping the flow of electricity and turning off the light.
What happens when a light bulb burns out?
When a light bulb burns out, it means that the filament inside the bulb has broken or worn out, disrupting the flow of electricity and causing the bulb to stop producing light. The bulb will no longer work until the filament is replaced.
What must be true for a circuit to light a bulb?
For a circuit to light a bulb, there must be a closed loop for the flow of electricity. This loop typically consists of a power source (e.g. battery), wires, a switch, and the bulb. When the switch is closed, the circuit is complete and electricity can flow through the wires to the bulb, causing it to light up.
How does the flow of electricity through a light bulb connected to a battery with wires affect the brightness of the bulb, and what factors should be considered in this scenario?
The flow of electricity through a light bulb connected to a battery with wires affects the brightness of the bulb. Factors that should be considered in this scenario include the voltage of the battery, the resistance of the wires, and the wattage rating of the light bulb. Increasing the voltage or wattage will make the bulb brighter, while increasing resistance will make it dimmer.
