Wheatstonen.

Brit.

/ˈwiːtstən/,

/ˈwiːtstəʊn/, U.S.

/ˈ(h)witˌstoʊn/

Etymology: < the name of Sir Charles Wheatstone, who in 1843 brought into notice the ‘differential arrangement’ apparatus, which had been invented by S. Hunter Christie in 1833.

a. Wheatstone bridge n. (also Wheatstone's bridge) a simple circuit for measuring a resistance by connecting it so as to form a quadrilateral with three known resistances and applying a voltage between a pair of opposite corners: a galvanometer connected between the other two corners registers no current when the ratios of the two pairs of adjacent resistances are equal.
