Why can acids conduct electricity?

The propagation of an electrical current depends on the passage of charged particles.


And when a strong acid, say #HX# dissolves in water, TWO such charged particles result, i.e. #X^-#, and a species we conceive as #H^+# or #H_3O^+#. And both of these ions allow passage of electric charge, i.e. the solutions are conductive.

On the other hand, for weaker acids, there are LESS charged particles in solution. And thus these acids are LESS conductive.
