Portrait of inventor Nikola Tesla, known for his work on alternating-current electrical systems.

Clue explained

Nikola Tesla was an inventor whose work helped make alternating-current electricity practical for delivering power over long distances. His designs for AC motors and power systems became part of the electrical infrastructure that spread in the late 19th century. Tesla worked with industrialist George Westinghouse, whose company backed AC technology during a fierce contest with Thomas Edison’s direct-current system. The unit of magnetic flux density, the tesla, was later named in his honor.
