Electricity - Wikipedia

Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge.In the early days, electricity was considered as being unrelated to magnetism.Later on, experimental results and the development of Maxwell's equations indicated that both electricity and magnetism are from a single phenomenon: electromagnetism.
