Who discovered electricity?We do not have an exact discoverer of

electricity but we know it was discovered in Greece.

The Greeks discovered that rubbing fur and tree resin caused an attraction between them.

There were other people who invented electric machines some centuries later.

When was it discovered?It is thought that electricity was discovered

around the year 600 B.C.

It was found in the form of magnetism.

What was the first application for electricity?The first application for electricity was a large battery used to build an electromagnet that had a lot of power. It was invented by Joseph Henry. He finished building it in 1831.

What was it for?This battery was used to build an

electromagnet.This electromagnet was used to lift very

heavy loads such as metals.

How long was it running?This application was running for two years, from 1829 to 1831, because after this application, a new one was invented.

Nowadays this kind of applications have evolved and they are a lot different.

What was the first electric machine?Otto von Guericke (1602-1686) was the one who first invented an electrostatic generator in 1672.

He observed that his machine could produce a repulsion.

This machine took out sparks from a sulphur globe.

Parts of the machineThis machine consisted of a sulphur globe moved by

a handle, on which a charge was induced.

Where did the energy come from?The energy of this electrostatic generator

came from a piece of ambar.The energy of the piece of ambar was later

transported to a sulphur ball.This sulphur ball was the source of energy of

the generator.The generator transformed kinetic energy

into electrical energy.
