We show that a comparison of the capacities of suitable condensers gives an inequality for the Schwarzian derivatives of a holomorphic $p$-valent function defined on the unit disk and ranging in a given domain of the complex plane. If that domain is a disk as well and the function is univalent, then this inequality essentially coincides with the classical Nehari inequality. The cases of equality in the resulting relation are discussed.
Keywords: Schwarzian derivative, $p$-valent function, holomorphic function, condenser capacity, Green's function.
