Introduction to Electricity

Electricity is a natural phenomenon that can be used to power equipment and electronic devices.

Atoms are present everywhere in space, these atoms have electrons. Electricity is the flow of electrons from one atom to another. This flow is called "electric current". Atoms that easily exchange electrons are called conductors. 

 The History of Electricity

Humans have been using electricity for less than 300 years, the concept of electricity has been known for thousands of years, but it wasn't until the 1880s that this resource made its way into our daily lives. Adaptation to electricity enabled the second industrial revolution and paved the way for modern society.

Electricity Measurement  

We measure electricity in watts. This name comes from James Watt, to whom we credit the invention of the steam engine.

The Origin of Electricity

Electricity sources fall into two categories:

·         Renewable sources naturally renew themselves quite quickly, for example: nuclear, hydroelectricity, wind and solar energy. 

·         Non-renewable sources are exhaustible such as coal, oil and gas
