Electrical work, Physics

Electrical work:

Electrical work is done if a quantity of charge (coulombs) is moved between two points which are at different electrical potentials.

  • The SI unit of work is the 'joule'. One joule of work is done when a charge of one coulomb moves through a potential difference of one volt.

          Electrical Work (joule)  =  Charge (coulomb)  ´  Potential Difference (volt)

                   Work  =  Q *  V  joules

  • Since one coulomb is one ampere second

                   Q   =  I  *  t

          then Work  =  V  *  It   joules
