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
Sound and mechanical energy.
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 electric bell, electrical energy is converted int sound energy.
An energy transformation is the change of energy from one form to another. Energy transformations occur everywhere every second of the day. There are many different forms of energy such as electrical, thermal, nuclear, mechanical, electromagnetic, sound, and chemical.
Kinetic energy is converted into electrical energy.
Heat.
Electrical energy, converted to mechanical energy by an electric motor.
The acoustic energy gets converted into electric energy
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.
Chemical energy
no
The most familiar example of this is running an electric motor.
