Artifact Overview
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.
