• The first knowledge about electricity existed people were aware of shocks from electric fish.

HISTORY OF ELECTRICITY

• In 1600, William Gilbert made a study of electricity and magnetism, distinguishing the lodestone effect from static electricity produced by rubbing amber

• The name of “electric” and “electricity” was taken from the New Latin word electricus, "of amber" or "like amber" from Greek word to refer to the property of attracting small objects after being rubbed.

HISTORY OF ELECTRICITY

• Electricity and magnetism were definitively linked by James Clerk Maxwell, in particular in his "On Physical Lines of Force" in 1861 and 1862.

• Electric charge is conserve.

PRODUCING ELECTRIC• Lenz law: The electic current is produce by

changing the mgnetic flux.
