Ionic compounds and some polar compounds are completely broken apart into ions and thus conduct a current very well.

A strong electrolyte is a solution in which a large fraction of the dissolved solute exists as ions.

A weak electrolyte is a solution in which only a small fraction of the dissolved solute exists as ions. The equation showing the ionization of a weak electrolyte utilizes a double arrow indicating an equilibrium between the reactants and products.

Summary
A strong electrolyte exists mainly as ions in solution.
A weak electrolyte has only a small amount of ionization in solution.
