Nikola Tesla is best known for his contributions to the design of the modern alternating current (AC) electricity supply system. His alternating current (AC) induction motor and related polyphase AC patents became the cornerstone of the polyphase system. This collection provides a remarkable insight into the very beginning of electric engineering.
