Thermal compensation can be provided in a Wheatstone bridge by ________(a) using more than one resistive sensor(b) making use of a heat sink(c) using cooling fans(d) immersing the circuit into a liquidThis question was posed to me in an interview.Enquiry is from Applications of Wheatstone Bridge in portion Measurement of Resistance of Electrical Measurements

Answer»

Right choice is (a) USING more than ONE resistive sensor

To explain I would say: By making USE of more than one resistive sensor within the four ARMS of a Wheatstone bridge we get a full bridge, half bridge or a QUARTER bridge setup with an automatic balancing effect.
