Energy timelines - electricity

   
Electricity is the flow of electrical power or charge. It is a secondary energy source which means that we get it from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power and other natural sources, which are called primary sources.
   
   
1752
After eons of superstitious imaginations about electricity, Ben Franklin figured out that static electricity and lightning were the same. His correct understanding of the nature of electricity paved the way for the future.
 
1820
Relationship of electricity and magnetism confirmed.
 
1821
First electric motor (Faraday).
 
1826
Ohms Law (G.S. Ohm).
 
1831
Principles of electromagnetism, induction, generation and transmission (Faraday).
 
1837
First industrial electric motors.
 
1839
First fuel cell.
 
1860's
Mathematical theory of electromagnetic fields published. Maxwell created a new era of physics when he unified magnetism, electricity and light. One of the most significant events, possibly the very most significant event, of the 19th century was Maxwell's discovery of the four laws of electrodynamics ("Maxwell's Equations"). This led to electric power, radios, and television.
