Electricity was seen to exist since times when amber and fur was rubbed together by the ancient Greeks, creating the output of static electricity.

The initial remarkable achievement in this area was by Alessandro Volta, an Italian physicist, who developed the 1st circuit in 1800. Actually is well liked demonstrated that a circuit has to be closed, or complete, to ensure electricity to circulate through it. Science fair experiments could be conducted using circuits that relate this principle.



Volta's student, Georg Simon Ohm, made the next discovery in 1826. He observed that things failed to allow electricity to give freely. Put simply, they resisted the flowing of electricity through them. This resistance of an circuit is measured by way of a unit called ohms which is abbreviated through the Greek letter omega (?).

Things allow electricity to advance through them whereas others don't let it to move very well. Those materials that allow electricity to maneuver through them are called 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 use copper wire as being a conductor and plastic coating being an insulator.
