In fact, this view is a quintessence of the Membrane Paradigm of black holes which suggests that the event horizon, or rather the so-called stretched horizon, is similar to a rotating conducting sphere of finite resistivity. In this paper we argue that this interpretation is rather misleading and the proper explanation of the Blandford-Znajek mechanism has to be sought in the properties of the ergospheric region of b","authors_text":"S.S.
