Paiting about William Gilbert (1544 - 1603)Image via Wikipedia

William Gilbert The term 'electricity' was coined by English pysicist William Gilbert (1544 - 1603) based on the Greek word 'elektron' for amber. Gilbert re-discovered what the Greeks had already observed, namely that amber could attract small stuff like dust particles when rubbed with a piece of fur.2

The American Benjamin Franklin FRS3 (1706 - 1790) experimented with electricity using a kite, a key and lightning, proving lightning was a form of electricity. He also deduced the fact that two items can be charged negatively and positively. He coined these, and most of the other words to do with electriciy, and also invented the lightning conductor.

Thomas Edison (1847 - 1931) made the light bulb economical, making electricity useful for the first time. He also helped define how electricity works.

Alessandro Volta (1745 - 1827) invented the Battery in 1800, though electricity was known about since the Greeks.

The german Prof. Georg Simon Ohm (1789 - 1854) published his law on resistance in 1827 

Did you know: Voltmeter is used to measure the differance in potential between two points.
