Electricity is one of the most important resources from the 18th century until the present. Electricity is essential to modern life nowadays. There are many ways to make electricity, including dynamos, generators, electricity from steam, hydroelectricity from falling water, burning coal, and solar power from the sun. Electricity is the movement of electrons through the other atoms. Metals are usually better conductors, while plastics and rubber materials are things called insulators. There are two types of electricity: DC, or direct current, and AC, or alternating current. AC can reverse directions, DC travels in a single direction. Electricity travels at the speed of light which is more than 186,000 miles per second.
History of electricity
Benjamin Franklin discovered electricity in 1752 by tying a metal key to a kite and flying it in a thunderstorm. When lightning hit the kite it traveled down the string to the key. Benjamin Franklin got a little shocked, but he survived. The first ever use of electricity was the light bulb in 1879 made by Thomas Edison which lasted for 40 hour. Next, the new bulb that was made lasted for 1200 hours. In 1800 Alessandro Volta invented the battery. The main elements of batteries are lithium, nickel, graphene, aluminum oxide, polyvinylidene fluoride, and ramsdellite. There are three main parts of batteries the cathode, electrolyte and the anode. The cathode is the positive side, and the electrons go through the wire and to the anode. The anode the negative side. and the electrons come into the battery through the electrolyte. The electrolyte is where a chemical reaction happens that makes the electricity, then goes to the cathode and goes through again. In the early 19th century, Charles Babbage was called the “father of the computer” because he invented the first programmable computer. He started all the programmable electronics. In 1891, Nikola Tesla invented the tesla coil. Tesla coils expel so much energy that it breaks the electromagnetic field and makes sparks. Enough electricity can make musical notes. Some people have made songs like The Legend Of Zelda Main Theme and other things.
Uses of electricity
People use electricity for lighting, heating, cooling, refrigeration, and for operating appliances such as computers, TVs and toasters, electronics, machinery, residential, entertainment, and public transportation systems. Police use tasers that apply electricity to paralyze their target. Electricity can be used to make radio waves. Radio waves can be picked up by antennas. Satellites use radio waves to broadcast images of space and earth. Residential, home appliances use up the most electricity at 38.5%, followed by commercial which uses 36.2%. Finally, is industrial which uses about 25.1%.
What happens if electricity comes in contact with a human
You skin will protect the first 99% of the current then when the electricity breaks through it zaps through your whole body and burns your internal organs. If your hand brushes the source, it will shock you, but you may survive. If you are holding the source, the muscles in the hand that allow you to make a fist will clench. If you were holding the electricity's source, you would not be able to let go would and it would get worse. DC will stop the heart while AC will make it flutter (which will not pump enough blood and you will die). If you do not die from the heart being unable to pump blood, the electricity will burn you. Some people have survived a lightning strike. The electricity traveled through the earphones she was wearing and into her phone. It burned her clothes but sophie lived. There is also a thing called ground current, when the lightning: strikes the ground but the current goes through the ground and shocks you. There are three types of lightning staccato lightning, forked, ribbon and bead lightning.
In conclusion, the tesla coil, radio waves and the uses of electricity are all tied to one thing, the invention of electricity. For 137 years, we have had electricity and some people can not live without it. Benjamin Franklin started the revolution of electricity. Electricity can jump from place to place. If anything is wet, it will travel farther. Be very careful when handling electric materials.
