01

Artifact Overview

To make money selling electricity, Thomas Edison had to know how much his customers used. This meter used electricity to plate zinc onto electrodes. By weighing the electrodes to see how much zinc had accumulated, Edison's company could calculate how much electricity was being used. Meters like this remained in service in some installations well into the 1890s.
