• The process of dissociating a liquid into ions when electric current is passed through them is called electrolysis or conductors of second kind. The arrangement used to study electrolysis is called a Voltameter. It contains a vessel, two electrodes, a solution called electrolyte & dc power supply.
  • Current inside electrolytes is due to motion of both + ve & – ve ions. i.e. I = I+ + I–  also I+ ≠ I–. 
  • Electrolysis obey Ohm’s law for small currents if V applied > V back.
  • Conductivity of electrolytes is 10to 106 times smaller than that of metallic conductors.
