- Federal Electric Company Transformer, circa 1906 - Transformers increase or decrease voltage and are essential to alternating current (AC) power systems. In the late 1800s, with the help of transformers, AC power systems proved more efficient and economical than their direct current competitors. Transformers helped convert electricity to high voltage for transmission across long distances, then reduced it to lower, safer voltages for use in homes and factories.

- Willis Straight Line Wattmeter, 1907-1919 - Wattmeters are used to test and measure electric power. Their development and design improvements grew as electric power generation expanded in the late 19th- and early-20th centuries. The Willis Electric Meter Company sold this commutator-type wattmeter in the early 1900s. It was manufactured by the Federal Electric Company of Chicago, Illinois.
