Who discovered electricity?We do not have an exact discoverer of electricity butwe know it was discovered in Greece.

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

There were other people who invented electricmachines some centuries later.

When was it discovered?It is thought that electricity was discovered around theyear 600 B.C.

It was found in the form of magnetism.

What was the first application forelectricity?The first application for electricity was a large batteryused to build an electromagnet that had a lot of power.

It was invented by Joseph Henry. He finished building itin 1831.

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

This electromagnet was used to lift very heavy loadssuch 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 wasinvented.

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

What was the first electricmachine?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 transportedto a sulphur ball.

This sulphur ball was the source of energy of thegenerator.

The generator transformed kinetic energy intoelectrical energy.
