Electricity is the transfer of electric charge, often by a conductor like copper wire. Most electricity that we use is generated by power stations by converting other forms of energy, such as chemical, mechanical, solar, or nuclear energy, into electricity.
There are two types of electricity: current electricity, which is the flow of charges that continues in electric circuits, and static electricity, which is the kind you get when you rub a balloon.
When Was Electricity Invented?
The earliest records go back to approximately 600 B.C. When the Greek philosopher Thales observed static electricity when amber was rubbed with fur.
The voltaic pile, created by Alessandro Volta in 1800, was the first workable method of generating electricity from a chemical battery. This was a breakthrough. Michael Faraday in the 1830s made the discovery of electromagnetic induction, which was applied to electric generators.
Thomas Edison built one of the first commercial power plants in New York in the later 1880s, and Nikola Tesla developed alternating current (AC) systems, which are the norm today for delivering power over long distances.
How Is Electricity Measured or Calculated?
Electricity is measured using a combination of three basic units: voltage, current, and power.
- Voltage (V) is the force that pushes electric charges through a circuit.
- Current (A) is the flow of electric charge, measured in amperes.
- Power (W) tells us how fast electrical energy is being used or generated.
The relationship between them is described by a simple formula:
W = V × A
We can determine how much electrical energy is being transferred in a system at any given time with the use of this equation.
