When light energy is absorbed by an object, it causes the object's molecules to vibrate and move faster, which generates heat energy. This transformation occurs through a process called conversion of light energy into thermal energy.
The four forms of energy that electricity can transform into are heat energy, light energy, mechanical energy, and sound energy.
A light bulb in an electrical circuit transforms electrical energy into light energy and thermal energy (heat).
Light energy can be transformed into other forms of energy such as heat, electrical energy, or chemical energy. For example, solar panels convert light energy from the sun into electrical energy, while incandescent light bulbs transform electrical energy into light and heat energy.
Conservation of heat
A device that uses a resistor to transform electrical energy into light and heat is an incandescent light bulb. The resistor, also known as a filament, has high resistance, which causes it to heat up and emit light as a result of the electrical current passing through it.

An electric bulb, like an incandescent or LED bulb, can turn electric energy into heat and light energy. An electric motor can transform electric energy into motion energy.
An example of a device that can transform electrical energy into light, heat, and sound is a typical household incandescent light bulb. When electricity flows through the filament of the bulb, it generates light by producing heat, and also produces sound in the form of a faint humming noise due to the vibration of the filament.
The transformations that you describe are quite common. Fire does this. Chemical energy in (for example) wood, transforms into heat when you burn the wood, and when you get enough heat, you will then also get light; in a fire, you get a glowing, very hot gas called plasma.

Materials like LEDs, phosphors, and semiconductors can convert electrical energy into light through a process of electroluminescence. Similarly, certain chemical reactions, such as those in glow sticks or fireflies, can also convert energy to light. In addition, some materials like incandescent bulbs transform electrical energy into heat, which then emits light.
Electrical energy can transform into various forms of energy, including heat energy, light energy, mechanical energy, and sound energy. This transformation occurs through different devices such as heaters, light bulbs, motors, and speakers.
