Definitions of REFLECTING GALVANOMETER
Sort: Oldest first
Of Sir William Thomson, a galvanometer in which several short magnetic needles are fastened to a silvered glass mirror, suspended by a silk thread in the midst of a coil of wire. A current passing through the wire causes deflection of the needles and hence of the mirror which casts a luminous reflection on a graduated arc. This form of galvanometer gives a very delicate measure of the strength of the current.
