What is the useful and wasted energy in an electric heater a television an electric kettle headphones Thanks for your help?
The use ful energy from headphones would be sound , the wasteful would be battery power.
How does the amount energy in the batteries in a flashlight compare to the total amount of energy given off by the flashlight as light and heat?
There is more energy in the battery than that given off as light and heat for two reasons. 1) Some energy is lost due to resistance in the battery. As current flows, energy is lost to heating of the battery due to this internal resistance. 2) As the battery operates, the voltage falls until it is too low to heat the bulb to incandescence. Yet energy remains in the battery, but this last energy is at too low a voltage to be useful.

What is the cost of photoelectric energy?
It is quite expensive, compared to the energy you get from your power company. Just a common car battery for storing the energy - an essential part of such a system - costs you more, for each watt-hour, than what you pay the power company, since the battery doesn't last forever. Such a system is still useful in places that are not connected to the regular power grid.
What are batteries useful?

Is sulfuric acid useful?
Yes, sulphuric acid is a very useful chemical. It can be used to manufacture fertlilsers (superphosphates) and is also used as a battery acid in cars.
What is the voltage of a 12 V battery?
It depends on the state of charge. A fully charged lead-acid 12V battery will measure around 13.6V, the same battery at the end of useful charge will be approximately 10.5V
What can one do with a battery heater?
Battery heaters are useful in case the power goes out in the winter and you have no other form of heat. Battery heaters are also commonly used to aid in heating small areas such as an office.
