The light bulb By: Cade Powell And Brandon Alegria

 Purpose Well in the mid 1800s Humphrey Davy invented the light bulb to light up dark and darker places. Although the original had many flaws to be innovated. Main Functions To light up on contact with metal and electricity and to light up passages and ways. And that’s the main function, its not like you're going to through it at someone, right?!

 Humphrey Davy was the original inventor. Invented around the 1800s.  Well Humphrey Davy would make the glass out of carbon, and a small metal piece at the bottom of the bulb. When Davy made the battery for the light bulb he would get a wire and connect them together to emit the light. Though on the first slide includes more details.

 Quote: “ Genius is one per cent inspiration, ninety-nine per cent perspiration. Thomas A. Edison, Harper's Monthly, 1932

Well Joseph Wilson wanted to make an improvement to Davys light bulb, he succeeded. Although Thomas Edison did it better. So did Lewis.H.S. But Willis.r. improved it beyond anyone by making it not darken inside and last for some years. this ordinary appliance revolutionized the whole world.

 The technology used to make the light bulb was a man made battery, copper wire, carbon glass, tungsten filament, glass mount, screw thread contact, insulation, electrical foot contact, support wires, and inert gas.

 Original :Well the original wasn't as bright as the ones we have today. Also the original would burn out in a Matter of days, while the new ones can stay on for years. Today : Today's light Bulb wont burn out As fast as the ones Before. So basically its Twice as durable.

ExampleScienceTechnologyEngineeringMath Light bulbThey used chemicals to make light. Electric battery to make electric arc. To design the light bulb. Calculate how long it would stay on.

It Impacted The world in a serious way by not having to buy up to ten candles just to light up their house, but now they can get a light bulb that can give off enough light for you to see.

It impacted them in a negative way because the light bulb would not stay on for very long and did not give much light so they innovated the light bulb so it could stay on for 1500 hours.
