Why is water not used as a dielectric in the condenser?
Hypothetically - it can. But in practice beware. Water is often called the universal solvent.And that''s why its practical use as a capacitor dielectric would fail. The plates of the capacitor are metallic and eventually water will dissolve the metal creating metal ions in a solution and this will cause a conductive path - a failure of the dielectric.
