Wheat·stone bridge

(wēt′stōn′, hwēt′-) also Wheat·stone's bridge (-stōnz′)
n.
An instrument or a circuit consisting of four resistors or their equivalent in series, used to determine the value of an unknown resistance when the other three resistances are known.

[After Sir Charles Wheatstone (1802-1875), British physicist and inventor.]
