Mainly:
Thermal energy to electrical energy
The useful energy that comes out of a light bulb is primarily in the form of light and heat. The electrical energy is converted into light energy that illuminates the surroundings and heat energy that warms up the light bulb and its surroundings.
In an electrical iron, the useful energy is the electrical energy that is converted into heat energy, which is used to press and remove wrinkles from clothing. The wasted energy in an electrical iron is primarily in the form of heat loss to the surrounding environment, as well as in the form of sound energy and electromagnetic radiation. Efficient design and insulation can help minimize wasted energy in an electrical iron.
I wouldn't say that electrical energy "uses" other types of energy; probably you mean that you can convert other types of energy to electrical energy. Most types of energy can be converted to electrical energy, or actually all of them (as long as there is some useful energy left) - including heat energy, nuclear energy, chemical energy, mechanical energy, etc.
Chemical energy is transferred to electrical energy! :) :p
The generators transfer mechanical energy into very useful electrical energy.
Nuclear energy is not useful in powering a flashlight because it is not readily convertible into electrical energy that can power the light bulb in a flashlight.
The efficiency of the motor can be calculated as the ratio of useful output energy to input energy. In this case, the efficiency would be 70J (useful kinetic energy) divided by 100J (electrical energy) multiplied by 100% to get a percentage. So, the efficiency of the motor is 70%.
it is electrical to radiant and thermal I'm not sure about that answer i think it's electrical to light (useful energy) and thermal (which is the wasted energy)
Because it is freely available and it doesn't damage the environment.
Electrical energy is useful because it is fairly easy to convert mechanical energy (from turbines, for example) into electrical energy, it is fairly easy to transport electricity over long distances, and it is fairly easy to convert the electrical energy (for example, in your home) into several other types of energy.
Useful energy change in the solar cell is from light to electrical energy. Solar cells use the photovoltaic effect to convert sunlight into electricity by absorbing photons from sunlight and generating an electrical current.
