- Edison General Electric Company Ammeter, 1889-1892 - In the late 1800s and early 1900s, companies that supplied electricity to consumers needed a variety of instruments to regulate and monitor electrical output. These instruments were vital to the operation of power stations and needed to be accurate and rugged. Ammeters--used to measure the current in a circuit--could be found on switchboards or connected to motors and generators.

- General Electric Edison Number 6 Rheostat, circa 1892 - Rheostats vary the amount of electrical resistance in a circuit. They proved beneficial as the use of electrical power expanded in the late 1800s. Among their many applications, rheostats helped motors start safely, controlled motor speed, maintained a constant current in battery chargers, and adjusted volume and light levels.
