Science Behind Electricity
September 20, 2016
Electricity is everywhere and there is simply no way that you can avoid it. Even if you become a hermit and renounce the world and go off the grid, you’ll have electrons jumping around you wherever you are and might even get struck by lightning which is again high voltage electricity.
Now to come to the SCIENCE behind electricity – it is a physical manifestation of the flow of electric charge which are properties of subatomic particles. Electrically charged matter is the cause of electromagnetic fields and can be either positive or negative. Electric charges produce an electrical field which in turn works on other electric charges to set up electric potential measured in volts. So next time electricians in Melbourne talk about volts in your home or office, you know what they are referring to.
A very common term used by people is electric current. It is measured in amperes and is the flow of electrically charged particles. These moving particles produce a magnetic field. It works in a cyclic order – electric currents generate magnetic fields and when magnetic fields are changed it produces electric currents.
Electricity basically has two aspects. The first is electrical power which is used to activate all electrical equipment. This is what people are generally aware of and is what lights up your room when you hit the switch. The other is electronics which deals with electrical circuits. These are the main components of diodes, vacuum tubes, transistors, integrated circuits and other similar active electrical parts.
While man might take credit for inventing electricity, it is actually not so. What has been harnessed is basically an understanding of the science behind electricity. Forms of electricity that exists in nature include lightning, in touch, friction and chemical bonding.
