ରେନ୍‌ହୋଲ୍ଡ ରଡ଼େନ୍‌ବର୍ଗ

 ରେନ୍‌ହୋଲ୍ଡ ରଡ଼େନ୍‌ବର୍ଗ (Reinhold Rudenberg) (୪ ଫେବୃୟାରୀ, ୧୮୮୩ – ୨୫ ଡିସେମ୍ବର, ୧୯୬୧) ଜଣେ ଜର୍ମାନ - ଆମେରିକୀୟ ବିଦ୍ୟୁତ ଯନ୍ତ୍ରୀ ଏବଂ inventor, credited with many innovations in the electric power and related fields. Aside from improvements in electric power equipment, especially large alternating current generators, among others were the electrostatic-lens electron microscope, carrier-current communications on power lines, a form of phased array radar, an explanation of power blackouts, preferred number series, and the number prefix "Giga-".
