Benjamin Franklin

The well known inventor made important discoveries about harnessing electricity. He was sure that there was electricity in lightning and that it could be harnessed, through his experiments he invented the lightning rod which conducted electricity from lightning and prevented structures from being damaged by strike.

Thomas Edison

Edison, known best for his work perfecting the first long - lasting commercially available light bulb, also invented the phonograph, a device that could record a voice and play not back.

He is also renowned for his work with direct current DC electricity and the power grid system which generated electricity and delivered it through wire networks.

Nikola Tesla

A name that will appear on every list like this one is Nikola Tesla.

Tesla is best known for helping perfect AC electricity a technology which went up against Edisons DC technology as a better, safer way to conduct electric currents.

During his career, Tesla also patented the AC motor and helped refine the transformer , which was later licensed to George Westinghouse for use with am AC motor grid.

George Westinghouse

Westinghouse was a pioneer in nperfecting the power grid. He studied Edisons power grid and decided he could improve it by using AC technology as DC woukld be difficult to scale, as it involved string currents and loss of power.

AC electricity combined with transformers was adaptable for widespread use and did not involve the same power loss as DC.

The AC vs DC power grid debate proved to be a bitter point of contention between Edison and Westinghouse's , AC won.

Thomas Murray

Using his engineering skills, Murray is credited with modernizing and making sense of the early power grids of New York City. He was able to redesign early power plants so nthatbtheybran more efficiently and at a less cost than earlier more old designs.

Murray`s important work also included his patented electric fuse box and the fuse plug.

He developed many devices in fields such as:

1. electric power generation

2.mass communication

3.sound recording

4.motion pictures

Inventions amongst others:

1.phonograph, phonomotor, telegraph

2.motion pictures camera

3.electric light bulb,

4.organized science and teamwork

5.first industrial research laboratory

6.carbon microphone

The point of this coil is to make small amounts of electricity and show it like lightning.

The bigger it is the more power it has.

There's a type of Tesla coil that can make music like a radio.

It will be painful if you touch it so be careful next to it.

Richard Portelli

Benjamin Franklin died at age 84 on April 17, 1790, in Philadelphia, Pennsylvania.

Benjamin Franklin was the 4^th wealthiest American when he died.

Benjamin Franklin had three kids called William Franklin, Sarah Franklin Bache and Francis Folger Franklin.

Benjamin Franklin’s slogan is ‘join or die’.

On June 10, 1752, Benjamin Franklin took a kite out during a storm to see if a key attached to the string would draw an electrical charge.

Benjamin Franklin didn't discover electricity in fact William Greener, Wilhelm Emil Fein and Schuyler Wheeler invented electricity.

Thomas Edison was an American inventor and businessman. He was born in 1847 and died in 1931. He developed many devices such as the phonograph, The motion picture camera, and early versions of the electric light bulb.He is also famous for improving the telegraph and telephone. A fun fact about Thomas Edison is that he setup his first lab in his parents' celler at the age of 10!
