Abstract

An investigation of the effects of bridge arm configuration, i.e., arm impedance ratios, of a Wheatstone bridge circuit are presented. Although the generalized treatment given can be applied to any resistance change transducer in a Wheatstone bridge, particular emphasis has been placed on the use of thermistors in solution phase calorimetry. The work presented characterizes the various bridge configurations in terms of their sensitivity, linearity, and theoretical temperature resolution.
