Extremal black holes are states in the non-perturbative spectrum of Supergravity theories. They may be charged under abelian fields and in this case give rise to an effective potential for the scalars. This, in addition, is responsible for the occurrence of an attractor mechanism: extremal solutions are determined by critical points of the effective potential. This implies that their supersymmetric features rely only on the algebraic properties of the electric-magnetic duality group. In this thesis black holes solutions and their properties under duality transformations are analyzed in extended Supergravity theories in four dimensions.
