Define electricity

Electricity is defined as the rate of flow of charges in a conductor.


The charges move from one end of the terminal to the other end. It generally moves from a positive terminal to a negative terminal. As the nucleus loosely holds the electrons, they travel freely within the limits of the body. The SI unit of electric current is Amperes.

An electric generator is a device for converting mechanical energy into electrical energy. The process is based on the relationship between magnetism and electricity. When a wire or any other electrically conductive material moves across a magnetic field, an electric current occurs in the wire.

  • Electricity is measured in units of power called watts. It was named to honor James Watt, the inventor of the steam engine.
  • A kilowatt represents 1,000 watts.
  • A kilowatt-hour (kWh) is equal to the energy of 1,000 watts working for one hour.
  • The force applied to electrons to push them through the conducting wire is known as voltage, and the rate of flow of the electrons is known as current.
