Electricity was known to exist since occasions when amber and fur was rubbed together by the ancient Greeks, resulting in the production of static electricity.

The 1st remarkable achievement in this field was by Alessandro Volta, an Italian physicist, who developed the first circuit in 1800. Actually is well liked showed that a circuit have to be closed, or complete, for electricity to flow through it. Science fair experiments could be conducted using circuits that demonstrate this principle.



Volta's student, Georg Simon Ohm, made the subsequent discovery in 1826. He observed that things would not allow electricity to pass through freely. To put it differently, they resisted the flowing of electricity through them. This resistance of the circuit is measured with a unit called ohms which is abbreviated from the Greek letter omega (?).

Some materials allow electricity to advance through them whereas others don't let it to move so well. Those materials which enable electricity to go through options are known as conductive materials. Those materials that resist the passage of electricity through choices called insulators. The resistance of conductive materials are low whereas the resistance of insulators is high. We can easily use copper wire as a conductor and plastic coating as a possible insulator.
