It is converted to heat first; this heat is then used to produce superheated steam. The pressure of the steam is what drives the electric generators.
No, an electric motor does not convert chemical energy to mechanical energy. Electric motors convert electrical energy into mechanical energy by using electromagnetic fields to create motion.
To convert electric energy into light energy
Flashlights convert electric energy to light energy and heat energy.
Electric energy can be changed into other forms of energy by devices such as electric motors, which convert electrical energy into mechanical energy; light bulbs, which convert electrical energy into light and heat energy; and electric heaters, which convert electrical energy into thermal energy.
convert chemical energy into electrical energy
convert chemical energy into electrical energy
Circuits convert electric potential energy into other forms of energy such as light, heat, or mechanical energy depending on the components within the circuit.
heat(useful energy) and sound(waste 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.
It converts electric energy to thermal energy
Radiant (light) energy.
Heat. Electric blankets are simply a resistance coil, which convert electrical energy to heat.
