Electricity is a physical phenomenon whose origins are the electric charges and whose energy is manifested in something mechanical, thermal, light and chemicals, among others. It can be seen naturally in atmospheric phenomena, such as rays, which areelectrical discharges caused by energy transfer between the ionosphere and the earth's surface (complex process that the rays are only one part). Other electrical devices may be found in natural biological processes and the functioning of the nervous system. It is the basis of how many machines, from small appliances to large power systems andhigh-speed trains, and all electronic devices. It is also essential for the production of chemicals such as aluminum and chlorine.

ELECTRICIDAD-ELECTRICITY
La
electricidad es un fenómeno físico cuyo origen son las cargas eléctricas y cuya
energía se manifiesta en fenómenos mecánicos, térmicos, luminosos y químicos,
entre otros. Se puede observar de forma natural en fenómenos atmosféricos, por
ejemplo los rayos, que son descargas eléctricas producidas por la transferencia
de energía entre la ionosfera y la superficie terrestre (proceso complejo del
que los rayos solo forman una parte). Otros mecanismos eléctricos naturales los
podemos encontrar en procesos biológicos, como el funcionamiento del sistema
nervioso. Es la base del funcionamiento de muchas máquinas, desde pequeños
electrodomésticos hasta sistemas de gran potencia como los trenes de alta
velocidad, y de todos los dispositivos electrónicos. Además es esencial para la
producción de sustancias químicas como el aluminio y el cloro.
