The concept of the electric field was first introduced by 19th century physicist Michael Faraday. It was Faraday's perception that the pattern of lines characterizing the electric field represents an invisible reality.
The strength of the electric field is measured in units of volts per meter (V/m). Electric fields often are present even if the equipment is turned off, as long as it remains connected to the power source. Electric fields decrease rapidly the further you get from the source.
