all you need to know about energy!!!!
Alessandro volta made the first battery in the 1800's. his batterys weren't practical because they were to big they were the size of a classroom. so he decided to use his batterys and make another branch of science called electrochemistry. some archaeologists believe that alessandro did not make the first battery because they found 3000 year old batterys made in baghdad that were made of clay.there is one thing that batterya have in common which is they all have stored chemical energy. that is ready to be turned into electrical energy. some batterys can hold more energy bacause of there capacity and it also depend on what the electodes and electrolytes are made of. there are two mane types of batterys which are dry cell and wet cell. a wet cell is like a car battery that is 12 volt to power bigger things such as cars and tractors and ect. a dry cell battery has a interior of a zinc-carbon dry cell. it is filled with lots of electrolyets (mno2) which is a type of paste. this battery powers little things like flashlight toys and ect. =http://=http://!!!THIS CONCLUDES MY BLOG HOPE YOU ENJOYED AND LEARNED LOTS=http://=http://!
