Who discovered electricity?Who discovered electricity?

The first contact with electricity was in the 600BC when the The first contact with electricity was in the 600BC when the Greeks discovered that rubbing fur in amber the obtain attraction Greeks discovered that rubbing fur in amber the obtain attraction between objects. Actually, the discovered static electricity. Some between objects. Actually, the discovered static electricity. Some archeologist in the 1930s found objects of the ancient Romans and archeologist in the 1930s found objects of the ancient Romans and

Persians similar to a modern battery.Persians similar to a modern battery.

Some people say that was Ben Franklin the one that discovered Some people say that was Ben Franklin the one that discovered electricity, but he only provided that electricity can be condact.electricity, but he only provided that electricity can be condact.

The first object that use electricity as energy resource was the The first object that use electricity as energy resource was the electric battery invented by Alessandro Volta.electric battery invented by Alessandro Volta.

The first object that make electricity as an useful resource of energy The first object that make electricity as an useful resource of energy was the incandescent light bulb, invented by Thomas Edison.was the incandescent light bulb, invented by Thomas Edison.

So we can say that electricity has been discovered over the So we can say that electricity has been discovered over the centuries.centuries.

What a machine!!!What a machine!!!

The first person who invented The first person who invented something that used electricity as something that used electricity as energy for working could be used by energy for working could be used by all people was an Italian scientist all people was an Italian scientist named Allesandro Volta,In 1800 he named Allesandro Volta,In 1800 he invented the elctric battery. Pherhaps invented the elctric battery. Pherhaps thank to him we have now a days new thank to him we have now a days new technological machines.technological machines.

The machine it is mainly of silver, The machine it is mainly of silver, paped soaked with salt water, and paped soaked with salt water, and zink. It does not work with the same zink. It does not work with the same efficiency that those we use today efficiency that those we use today but obviusly they did not have the but obviusly they did not have the same technology that the ones we same technology that the ones we used today for charge our mobile used today for charge our mobile phone.phone.

Application of electricityApplication of electricity -What was the first

application for electricity?

We consither the first aplicattion of electricity was the battery by Alessandro

Volta in 1800.

What was it used for?

It was used as a primary source generator, and you can get to it through the

poles.

Application of electricityApplication of electricityHow long were it running? So How long were it running? So if it was an object, how long if it was an object, how long

did it last?did it last?

  -We continue using the -We continue using the battery in our daily live, we battery in our daily live, we

consider they last until today consider they last until today but they aren´t useful when but they aren´t useful when they give out their energy.they give out their energy.
