The Power of Light
What Is An Incandescent Light Bulb:
An incandescent light bulb is a recistence in an electric circuit that transforms electric energy into light energy and heat energy generatinging a visible light.
Origin Of The Incandecent Light Bulb:
In the XIX century scientists tried to make incandecent light bulbs, the first one to succed was Humphry Davy by using a platinum filament in the joule effect at the year of 1802. After many tests with many different scientists Thomas Edson was the first one to create the first light bulb that went to the market on 1879, using coal as the resistence inside a glass with vacuum, here is how it worked. the heated coal started to glow thanks to its hight tempture but insted of burning in contact with oxygen the coal was placed inside a glass that laked one componet to make fire oxygen making the coal burn way slower than normal making the light bulb very durable.
Variables Of A Light Bulb:
How to make a simple light bulb:
8 Batteries D
Wires
Lead ( the most costeffective filament )
Cup
Tape

Variables Of A Light Bulb:
- Brightness- why - differnt materials have differnt incandecence.
- Voltage - why - differnt materials will burn in diffent voltages
How to make a simple light bulb:
- Materials
8 Batteries D
Wires
Lead ( the most costeffective filament )
Cup
Tape
- Steps
- Make a siries circuit with the 8 batteries
- Conect the wires to the filament
- Touch the 2 tips in the 2 ends of the battries
- Wait until it heats.
