AC/DC basically stands for "alternating current/direct current" which is an indication that electricity is changing from an alternating current (e.g. from your wall outlet) to a 'direct current' (e.g. your T.V.). Brothers Malcolm and Angus Young felt that this perfectly symbolised the music they wanted to make (i.e. raw energy, performances driven by power and a sheer love of music).
