What type of energy those the light bulb use?
A light bulb typically uses electrical energy to produce light. The electricity flows through a filament or gas within the bulb, generating heat and light as a result of the resistance in the filament or the ionization of the gas.
Does the resistance of a filament light bulb change as the bulb gets brighter?
Yes, the resistance of a filament light bulb increases as the bulb gets brighter. This is due to the increase in temperature of the filament, which causes the resistance to go up.
What is the purpose of the filament in a light bulb with filament?
The purpose of the filament in a light bulb is to produce light when electricity passes through it, causing it to heat up and emit light.
Why is the filament wire of a bulb made very thin and given a helical shape?
The filament wire in a light bulb is made very thin to increase its resistance, which causes it to heat up and produce light efficiently when an electric current passes through it. The helical shape allows the wire to have a greater length within the bulb, maximizing the amount of light that can be produced.
What is the function of lead wires in a light bulb?
Lead wires in a light bulb are used to connect the filament to the electrical circuit. They conduct electricity from the power source to the filament, allowing it to heat up and produce light. Lead wires also provide support for the filament within the bulb.
Is resistance in the filament of a lamp essential or not?
Yes, the resistance of the filament of a light bulb is what generates enough heat to make the filament glow and produce light.
What type of energy those the light bulb use?
A light bulb typically uses electrical energy to produce light. The electricity flows through a filament or gas within the bulb, generating heat and light as a result of the resistance in the filament or the ionization of the gas.
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.
Does the resistance of a filament light bulb change as the bulb gets brighter?
Yes, the resistance of a filament light bulb increases as the bulb gets brighter. This is due to the increase in temperature of the filament, which causes the resistance to go up.
When the bulb is the resistance what this tells about the resistance?
An incandescent bulb has a filament that has a resistance. The value of the resistance determines the current that will flow for a given supply voltage. The heat generated by the current flowing through the filament gives off light. As the resistance of the filament decreases the current increases and you get more light.
Function of filament?
A filament is a thin rod like long structure usually cylinderical in shape i.e. open at both ends.
What does the filament of a light bulb allows the light bulb to change electrical energy to?
The filament of a light bulb allows electrical energy to be converted into radiant energy in the form of light and heat. When electricity flows through the filament, it heats up and emits light through a process called incandescence.
What is the purpose of the filament in a light bulb with filament?
The purpose of the filament in a light bulb is to produce light when electricity passes through it, causing it to heat up and emit light.

Why does the filament become hot?
The filament becomes hot when electricity passes through it, due to resistance in the wire. This resistance causes the filament to heat up and emit light in an incandescent bulb.
How is an electric current flow through the bulb to light it up?
The electrons flow into one end of the metal bulb bottom, they then flow into the filament where they meet heavy resistance. This resistance causes the filament to heat up and produce light as the electrons try desperately to keep moving.Another AnswerIn the case of incandescent lamps, the electricity does work on the filament, causing its internal energy to increase. This is accompanied by a rise in temperature which results in a loss of energy to the surroundings by (mainly) heat transfer and (to a lesser extent) electromagnetic energy in the form of visible light.
