Ensayo sobre la electricidad en inglés

The most powerful energy

The electricity is the presence and flow of electric charge. The ancient Egyptian write about the electricity referred to the electric fish how “the Thunder of theNile”, which protect to the other fishes. This idea was similar in the other cultures, like in the Mediterranean where the catfish’s shocks provoke headache. Until the year 1600 A.C. the English scientist,William Gilbert, made a careful study about the electricity and the magnetism.

The electricity easily can be obtained or produced, because it’s a chemical transformation, like the batteries, orthe heat. The facility of transport and distribute, like in the batteries, where various packages fitted in your pocket, or in 1 meter of wire you turn on your computer, or your videogame. Alladvantage is that this type of energy easily you can transform in a new or different, example, with only turn on a bulb, the electric energy turned in a calorific energy, or in an electrical drill, when youconnect the energy transform in a new energy.

Maybe you now think “the electricity is perfect”, but no, the electricity it´s the second dangerous energy (after of the nuclear energy), becauseeasily it´s conducted for your body, the water, the metals, etc. If you put a wire in water, all the water turn in electricity, and if you touch, you will have a serious shock that can be kill you.Other problem is that, it´s no transportable, and if is, is in small amounts, like the batteries, that only live 15 or 16 hours. And, for produce this energy, the human need contaminate, sometimes theplanet, like burn carbon, or waste gas in mega machines.

In conclusion, the electricity is good, but the humans have to be careful with themselves, and with the environment.
