What did they use before electricity?
Before electricity we used things like coal and oil, or earlier, we used wood for fires. And before lights we used candles and lanterns.
People use a lot of electricity, and often need to obtain it from many different sources in order to get enough. It is also true that windmills have other uses than the generation of electricity, and they were in use centuries before electricity came into use. You can mill grain without electricity, by connecting millstones to an axle, which is turned by the wind.
All the electricity you use has been created by humans. Electricity is energy which results from the behaviour of charged particles: electrons and protons. Electricity, as in electric current, can be created by man using machines such as generators to power tools and devices which are operated by electric power. Electricity can also occur naturally, and has done so since before humans were around to work out how to use it; lightning and static (frictional)…
humans don't need electricity they use it because its a luxury like excessive food and cable humans can survive without electricity all though its become a very common "necessity" but as people learn in schools i hope that civilizations before survived with out electricity but i could be wrong who knows what kids learn in schools these days lol
Electricicty is consumed when hooked to something which turns electricity into something else. A lamp turns electricity into light, and use something up in the process. A fridge use electricity to cool its insides, and use some of it up. A fan use electricity to move air around, and some of it is used up.
Why would you want to do that? "Using electricity" should never be a goal in an of itself. Using electricity has costs, both in money, and ecological.You would want to use electricity if it serves some useful purposes - basically, you use DEVICES that use electricity, because they do something useful for you.
I think so. -- Use electricity to charge a battery ==> it becomes chemical energy -- Use electricity to toast bread in the toaster ==> it becomes heat energy -- Use electricity to drive a golf cart ==> it becomes kinetic energy -- Use an electric crane to lift I-beams to the second story ==> it becomes potential energy -- Use electricity to run a fan ==> it becomes wind energy -- Use electricity to…
