Description:
Two different metal wires such as Chromel and Constantan ( Type E) are twisted together at each end. One wire is cut in the middle and a volt meter is placed across the cut wires to measure the potential difference that is produced by sticking each end into a bath of different temperatures; such as one twisted end in ice water and the other twisted end in hot water.
