Benjamin Franklin Theroy
Benjamin Franklin believed that lightning was electricity in action so he used a kite and a key. The same year, he made a lightning rod and put it on top of a house and when the lightning hit the rod it was short circuited to the ground leaving the house untouched. -
Guigi Galvani Discovery
Galvani made a connection with electricity and movement of muscles. He accidently noticed that a spark could make a dead frog's leg move. He experimented even more and concluded that the muscle moved because of electricity -
Wet-Cell Batteries
The wet-cell battery was made in 1800 by Alessandro Volta. It produced an electrical current. It had zinc and silver discs immersed in a solution of acid. The current flowed though a wore that connected the two discs. -
Hans Oersted Discovery
Oersted discovered that there is a connection between electricity and magnetism. He found that if an electric current flows though a wire, it created a magnetic field. -
Electric Motor
The eletric motor was made in 1921 by Michael Faraday. -
Transformer
The transformer was invented in 1831 by Michael Faraday. A transformer is a device ised to change the voltage of an electric current. -
