An electric doorbell uses electrical current thru a coil to move a metal bar using magnetism and cause it to strike a metal plate making a ring sound
The acoustic energy gets converted into electric energy
Three common methods are:Electrical energy (electric motors)Chemical energy (gasoline or diesel engines)Atmospheric thermodynamic energy (windmills)Some smaller pumps can also use solar energy, though this is just a variation of electrical energy since the solar energy is first converted to electricity to power an electric motor.
Kinetic energy.
Transformers inherently do not have frictional losses, but transformers and rotating machines perform completely different functions, so I'm not sure it is fair to compare them. Transformers are used to transform electric energy (the input is electric energy, and the output is electric energy). Rotating machines either take electric energy and convert it to mechanical/kinetic energy, or take kinetic energy and convert it to electric energy.
An electric motor converts electrical energy to kinetic energy.
In an electric bell, electric energy is converted into mechanical energy to produce sound. This is done through the electromagnetic force acting on the metal clapper to strike the bell and create the ringing sound.
An example of electric energy being converted into mechanical energy is when an electric motor is used to power a fan. The electrical energy is converted into rotational mechanical energy, which drives the rotation of the fan blades, creating air movement.
Heat.
Inside an electric cell, chemical energy is converted into electrical energy. When the cell is part of a complete electric circuit, the electrical energy is then converted into other forms of energy, such as light, heat, or mechanical work, depending on the components in the circuit.
Electric energy can be converted to kinetic energy through the use of electric motors, which transform electrical energy into mechanical energy to produce motion. Another way is through electric trains, where electric energy is used to power the motors that move the train along the tracks.
Electrical energy, converted to mechanical energy by an electric motor.

Chemical energy.
Electric energy can be converted into heat through resistive elements like heating coils or electric stoves. It can be converted into motion through electric motors, which use electromagnetic forces to generate rotational or linear motion.
Chemical energy
Electric energy can be converted into many things, all of them are other forms of energy. Electric energy can be converted into heat energy, like in many stoves and ovens. Electric energy can be converted into sound energy, which happens in speakers. Electric energy can be converted into mechanical energy, like with electric motors in fans and other devices. Electric energy can be converted into light energy as with a light bulb. Unfortunately, we do not currently have the technology to turn energy forms into matter as is shown in many sci-fi shows like Star Trek's replicators. Every energy is able to change its type. For example sound energy can be converted into electrical , light, heat and in many other forms.
Light bulb: Electrical energy is converted into light and heat energy. Electric heater: Electrical energy is converted into heat energy. Television: Electrical energy is converted into light and sound energy. Electric fan: Electrical energy is converted into mechanical and sound energy. Computer: Electrical energy is converted into heat and sound energy, as well as processing and display energy.
