The transformation of electrical energy to other energy

Thermal energy from electricity: When an electric current is passed through an electric heater or iron, the wire of the heater or iron becomes very hot. In this case, electrical energy is converted into thermal energy.
Electrical to mechanical energy: Passing current through an electric fan causes the fan to rotate. In this case, electrical energy is converted into mechanical energy.
Electrical energy to Light energy: When current is passed through an electric bulb, the bulb burns to produce light. In this case, electrical energy is converted into light energy.
Electrical energy to chemical energy: When electricity is passed through an electrolytic substance, the substance undergoes electrolysis to produce new substances. In this case, electrical energy is converted into chemical energy.
Electrical energy to sound energy: Electrical energy is converted into sound energy in telephone receivers, televisions, radios and electric bells.
Electrical energy to magnetic energy: An iron or steel bar wrapped with insulated copper wire and passing a current through the wire turns the bar into a magnet. In this case, electric energy is converted into magnetic energy

The transformation of light energy to other energy

Chemical energy from light energy: When light falls on a photographic plate or film, a chemical reaction takes place and an image is formed. Plant food is produced by photosynthesis in the leaves of plants in sunlight. In these cases, light energy is converted into chemical energy.
Electric energy from light energy: When light falls on a photo-electric cell, an electric current is generated. In this case, light energy is converted into electricity.
Light energy to thermal energy: When the laser beam falls on a metal, the metal is instantly vaporized. In this case, light energy is converted into heat energy.

The transformation of sound energy to other energy

Sound energy to mechanical energy: The window glass shatters and shatters due to the loud explosion. In this case, sound energy is converted into mechanical energy.
Chemical energy from sound energy: When acetylene is detonated in gas, the gas is dissociated into carbon and hydrogen by the explosive noise. In this case, sound energy is converted into chemical energy.
Sound energy to electrical energy: Sound energy is converted into electrical energy in the transmitter and microphone of the telephone.

The transformation of magnetic energy to other energy

Thermal energy from magnetic energy: If an iron bar is repeatedly magnetized and demagnetized, the bar heats up. In this case, the magnetic energy is converted into thermal energy.
Electric energy from magnetic energy: Winding a coil of conducting wire in a magnetic field causes current to flow through the coil. In this case, magnetic energy is converted into electric energy.
Magnetic energy to mechanical energy: When a bar magnet is brought near iron ore, the iron ore is attracted towards the bar magnet and sticks to the bar magnet. In this case, magnetic energy is converted into mechanical energy.
