D.E.V.I.C.E. is an encyclopedia of terms used by manufacturers of test and measurement equipment. T&M Atlantic created this service to better explain the functionality of instruments it offers, and to highlight the latest developments in the world of measurement equipment. We are using such tools as animation to bring words and pictures to life and to create not just an understanding but also an appreciation for technology that goes into the design of every instrument.

The name given to a region in an electric circuit in which charged particles would tend to move from one place to another. When using a gravitational analogy, potential difference is a difference in height. The greater the physical height in the analogy, the greater the potential difference in the electric circuit.
