Electricity

Electricity
Electricity is one of the most amazing scientific breakthroughs ever. If electricity had not been invented imagine what the world would be like today.In this day and age we are dependent on electricity for nearly everything. Lighting, heating, cooling, cooking, entertainment, science, research, work and even schoolwork.


History
Electricity was first discovered by Benjamin Franklin in 1750 when he suggested that lightning was a form of electricity and sought to prove it with an experiment in which an electrical conductor could extract electricity from a thundercloud. Before he could do this a French experimenter named Thomas-Francois Dalibird, who had heard about Benjamin’s predicament conducted a lightning strike with a 12.2 metre metal pole in May 1752. In June that same year Benjamin Franklin flew a kite with a key attached to it up into the sky in the middle of a storm and the key got struck by lightning. Now electricity is used in everyday life, like lightbulbs.


Ways To Generate It
Many people have found many ways to generate electricity. Some variations include solar power, nuclear power, wind power and hydropower which is water generated power). The majority of New Zealands power is made by hydropower. When using hydropower, to make electricity, there is a river and it goes through a pipe and up to the turbine which is attached to a generator. The river flow causes the turbine to spin and sending the hydropower up to the turbine which turns it into electricity therefore generating power. Wind power uses the power of the wind to create electricity. The wind turbines, as opposed to windmills which are more commonly used on farms, spin because of the wind blowing on it. The turbines send the wind power down the pole to a big battery underground, this converts it into electricity. Solar power is harnessing the power of the suns rays. Solar panels take in the rays of the sun and sends them to a charge controller, which sends the power to a battery system, which converts it into DC power and then sends the DC power  to an inverter which changes it to AC electricity


The Lightbulb
One of the main uses of electricity is the lightbulb. The first lightbulb like we have today was made by a scientist named Thomas Edison. Before the lightbulb that we have today, the lightbulb evolved massively over time. The first lightbulb ever invented was created by Joseph W. Swan in 1850 who was working on an incandescent lamp using carbonized paper filaments. Incandescent lamps light p by using electricity to heat up a thin piece of material. In 8179 Swan started installing lightbulbs in homes and soon nearly everyone had a light in their home. After that, the lightbulbs like we have today were created. The first lightbulb like we have today was made by a scientist named Thomas Edison.


Electricity is now one of the most important thing in peoples lives for nearly everything. We would not be where we are today without the invention of
Electricity.
