About electricity
>Mordern society relies heavily on the convenience and versatility of electricity.it power your microwaves help light your home ,let's you TV and so much more.
>Electric current is measured in ampears (amps).
>Electric potential energy is measured in volts.
>Two positive charges repel each other as do two negative charges opposite charges on the other hand attract each other.
>When an electric charges builds up on the surface of an object it creates static electricity in the from of a small electric shock which is what happens when the electric charges is quickly neutralized by an opposite charges.
>Electric cells can produce strong electric shock of around 500 voltsfor both self defence and hunting.
>Electric circuit can contain parts such as switches transformation resistors and transformers .
>A command way to produce electricity is by hydropower a process that electricity by using the water to spin turbines attached to generators.
>The world's biggest source of energy for producing electricity comes from coals .the burning of coal in campuses heats boiler water untill it becomes steam which then spins turbines .
>Lighting is a discharge of electricity in the atmosphere lighting bolts can travel at around 210,000 kph while reaching nearly 30,000c in temperature .
Electrical field work in a similar way to gravity with an important expections being that while gravity always attract electric fields can either attract or repulse .
American benjamin frankin carried out extensive electricity research in the 18th century inventing the lighting rod amongst his many discovers lighting rods protect buildings in the event of lighting by conducting lighting strikes through a grounded wire.
