About This Product
A meter bridge applies the Wheatstone bridge principle along a single wire: a jockey is slid until the galvanometer shows no deflection, and the balancing lengths give the ratio of the two resistances. Physics classes use it to find an unknown resistance and, with the wire length and diameter, the specific resistivity of a material. The Wheatstone Bridge Apparatus can be supplied on export terms to Cyprus, Lesotho, Kuwait, Albania and Ghana.
