Heat.
A light bulb can make heat and light.
In a light bulb, electrical energy is transformed into two primary forms of energy: light energy and thermal energy. As electric current passes through the filament, it heats up and emits visible light, producing light energy. Simultaneously, a significant amount of energy is also converted into heat, resulting in thermal energy, which can make the bulb hot to the touch.
both use an electric current running through a material that somewhat conducts electricity to produce heat, and the light bulb also uses it to make light
First let us understand the different parts that go to make up the light bulb shall we? The key component in a light bulb is the filament, this filament, ususually a thin piece of wire, is connected to two contact points. These points are then connected to the metal base of the bulb. When the bulb is attached to the light socket a circuit is then made. As the thin wire is part of the circuit it will have electicity passing through it when the power is switched on. The bulb glows because of the filament is thinner than that of the rest of the circuit. The filament gives off heat energy and begins to glow, this glowing we call light energy. You now have two forms of energy.
electric energy to mechanical energy
chemical energy
The electric light bulb.
Usually it is by pushing the switch on the wall into the down position. If that does not work, turn the bulb until it does not make contact and fix the switch.
Both normal and colored light bulbs typically have the same energy consumption in terms of electricity when producing light. The difference lies in the design of the colored bulb that filters out certain light wavelengths to produce colored light, which can make it appear dimmer compared to a normal bulb of the same wattage.

No, he called him and told him he should invent a incandescent light bulb though.
The glowing of an electric bulb is an example of a physical change. When electricity flows through the filament of the bulb, it generates heat and light, causing the bulb to glow. This process does not involve any chemical reactions or changes in the composition of the materials in the bulb. It is simply a conversion of electrical energy into heat and light energy, which is a physical transformation.
