The filament is fine so that its electrical resistance can be quite high. It is also long, for the same reason. Usually it is coiled up to fit the length in the lamp.
The heating effect of electric current is proportional to the current squared, time the resistance (I*I*R). Most of the effect is due to the current.
The current through the filament must be limited to stop it melting. Adding resistance will do that. Taking resistance away increases heating. So, a low energy lamp has a very thin filament and a high energy lamp will have a thicker filament.

How it functions electric lamp?
An electric lamp, also known as a light bulb, functions by using electricity to heat a thin filament inside a glass bulb. As the filament heats up, it produces light. The bulb is filled with an inert gas to prevent the filament from oxidizing and burning out quickly. When the electricity flows through the filament, it causes the electrons to jump and emit photons, creating light.
How does the electric lamp function using electricity?
An electric lamp works by passing an electric current through a filament inside the bulb, which heats up and produces light as a result of its high temperature. The filament is typically made of tungsten due to its high melting point. The light emitted is a result of the filament glowing white-hot when electricity flows through it.
Two lamps one with thick filament and one with a thin filament are connected in parallel to a battery . What explains why the lamp with the thicker filament burns more brightly?
The lamp with the thicker filament has a lower resistance compared to the one with the thin filament. According to Ohm's law, lower resistance allows more current to flow through the thicker filament when connected in parallel to the same voltage source. This increased current results in a higher power output (P = I²R), causing the lamp with the thicker filament to burn more brightly.
What part of a light bulb gives off electricity?
The part of an incandescent light bulb that gets hot and produces the light is called the filament.
What type of spectrum is produced by a filament lamp?
continuous emission
What type of light build glows when a filament inside it gets hot?
Electric lamps having incandescent filaments.
What energy change happen inside an electric lamp?
Inside an electric lamp, electrical energy is converted into light and heat energy. The electrical energy flows through the lamp's filament, heating it up to produce light. Some of the electrical energy is also converted into heat energy due to resistance in the filament.

Why Doesn't a lamp light up if the filament inside is broken?
If the filament inside a lamp is broken, it cannot conduct electricity properly, which is essential for generating light. The broken filament creates a gap in the circuit, preventing the flow of electricity needed to produce light. As a result, the lamp will not light up.
Which is the filament used in flouresent lamp?
The filament used in a fluorescent lamp is made of a coated tungsten coil. When electricity passes through the coil, it excites the mercury vapor inside the lamp, producing ultraviolet light that then interacts with the phosphor coating on the inside of the lamp to produce visible light.
When you turn on a lamp electric energy changes to what kind of energy?
When you turn on a lamp, electric energy is converted into light energy and heat energy. The electric current flowing through the lamp's filament generates heat, which in turn produces light.
What happens to the energy when you turn on an electric lamp?
When you turn on an electric lamp, electrical energy is converted into light energy and heat energy. The electrical energy flows through the lamp's filament, causing it to heat up and emit light. Some energy is also lost as heat due to resistance in the lamp's circuit.
How is energy transformed in an electric lamp?
In an electric lamp, electrical energy is transformed into light energy and heat energy. When the lamp is turned on, the electrical current flows through the bulb's filament, causing it to heat up and emit light. Some of the electrical energy is also transformed into heat energy due to resistance in the filament.
What type of energy is converted in an incandescent lamp?
Electric energy is converted into light and heat energy in an incandescent lamp. The electric current passing through the filament of the lamp heats it up, causing it to emit light as well as heat.
What is bicycle lamp made of?
It's made of plastic then there's a filament inside to make it light up.
What happens to energy from electricity when you turn on an electric lamp?
When you turn on an electric lamp, the electricity flows through the lamp's circuit, causing the bulb's filament to heat up and emit light. The electrical energy is converted into light energy and heat energy.
