Without it we would still be using candles to light houses and perhaps moving around with steam trains and wagons. without the electricity the world would have no evolution.
Thales of Miletus who lived in ancient Greece was a mathematician, philosopher, astronomer and engineer. It was this genius who discovered her.
THE electricity is the ability to perform a job through chemical energy or mechanical energy through turbines and generators that transform various forms of energy into electricity.
Between two points of a conductor, when a potential difference is applied, electrical energy is generated between its terminals.
Its main function is to generate other forms of energy such as mechanical and thermal.
Energy is identified as joule (J) in the international system of units but the most commonly used unit of average is kilowatt-hours (kWh).
In our country in 2015, 60% of the electricity produced came from hydroelectric plants and the rest came from nuclear plants Angra I and Angra II.
And also the energy comes from thermoelectric sources and renewable energy sources that are wind energy and biomass.
kWh is used to measure the energy consumption of a given location. The company multiplies the kWh unit cost by the amount of energy consumed during the days of the month.
Let's say that the consumption for the month of May was 120 kWh and the cost of 1 kWh is r$ 0.48, the energy bill for May will be:
C = 120 x 0.48
C = r$ 57.60
