______ is an example of a passive transducer that uses the variation in electrical resistance in wires to sense the ______ produced by a force on the wires.
Direction: It consists of two statements, one labelled as Statement (I) and the other as Statement (II). Examine these two statements carefully and select the answers to these items using the codes given below:Statement (I): A ‘strain gauge’ is an example of a ‘Transducer’ or an electromechanical transformer.Statement (II): In the ‘strain gauge’, displacement is used to vary the resistance of a circuit component and the ‘strain’ is measured in terms of the change in the resistance.
A resistance strain gauge is used to measure the stress of steel which is stressed to 1200 kg/cm2. If the gauge factor is 2.5 and Young’s modulus of steel is 2 x 106 kg/cm2, the percentage change in resistance of the gauge is
