  • Amperometry can be distinguished from voltammetry by the parameter being controlled (electrode potential E) and the parameter being measured (electrode current I which is usually a function of time – see chronoamperometry). [en]
  • In a non-stirred solution, a diffusion-limited current is usually measured, which is propor-tional to the concentration of an electroactive analyte. [en]
  • The current is usually faradaic and the applied potential is usually constant. [en]
  • The integral of current with time is the electric charge, which may be related to the amount of substance reacted by Faraday’s laws of electrolysis. [en]
