Important inventions in the field of electricity

Human lives were not as convenient and fun in ancient times as we know it today. Certain inventions played an important role in making all the differences from being medieval to being modern humans. Some important inventions in the field of electricity are listed below with the name of their inventor.

• Benjamin Franklin introduced a theory that lightning is electricity. He was the first person to coin two terms, positive and negative charge.
• James Watt invented the steam engine as he thought that this engine would replace animal power.
• William Thomson, also known as Lord Kelvin invented a temperature scale that was based on the concept of an absolute zero temperature (-273°C).
• Thomas Seebeck is best known for his discovery of the ‘Seebeck Effect’. He also introduced a theory called thermoelectricity.
• Michael Faraday discovered electromagnetic induction. Faraday worked on electric currents. He has the unit of capacitance, farad named in his honor.
• James Maxwell was an influential mathematician who translated Faraday’s theories into mathematical expressions. Maxwell also has the electromagnetic unit of magnetic flux named in his honor.
• Thomas Edison had 1093 patents under his name but he is best known for his invention of the light bulb.
• Nikola Tesla introduced the concept of Alternating Current that was an alternative of the Direct Current which was more costly.
• George Westinghouse invented the air brake system to stop trains and founded the Westinghouse Air Brake Company.
• Alexander Graham Bell is credited with patenting the first practical telephone. He has a unit of sound level ‘bel’ named in his honor.
