electricity can be useful in alot of things. You will not imagine how much you use electricity throughout the day. You mostly use it for light. right now you are using electricity while you are reading this. You use it when your watching TV, or playing video games, or using an air conditioning machine. that is how electricity is useful.
What else can I help you with?
What is the useful and wasted energy in an electrical iron?
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.
What form of energy that is not useful when a flashlight is on?
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.
What is the effiency of a motor that converts100j of electrical energy into 70j of useful kinetic energy?
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%.
Useful energy change in the solar cell is from light to?
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.
What is the useful energy in a radio?
The useful energy in a radio is the electrical energy converted into radio waves that transmit sound through speakers, allowing us to listen to music or news.
What is the energy transformation that produces useful energy?
Thermal energy to electrical energy
If electrical energy goes into a light bulb what useful energy comes out?
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.
What is the useful and wasted energy in an electrical iron?

What is useful energy transfer when coal is burnt?
Chemical energy is transferred to electrical energy! :) :p
What is the energy transform that happens in the generator?
The generators transfer mechanical energy into very useful electrical energy.
What form of energy that is not useful when a flashlight is on?
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.
What is the energy transfer in a light in the ceiling?
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)

Why is solar energy useful?
Because it is freely available and it doesn't damage the environment.
Why is energy electrical?
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?
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.
List several examples of how electrical energy and light energy are useful to you?
Electrical energy and light energy are useful to me in a variety of ways from the machines used to make the food you eat to the energy used to purify the water you drink. The clothes you wear are even dyed different colors from the light energy alone.
