Answer» CORRECT CHOICE is (a) (incremental change in RESISTANCE due to stress/resistance of an unstretched WIRE)(unstretched length of wire/incremental change in length) Easy explanation: Gauge factor is defined as(incremental change in resistance due to stress/resistance of an unstretched wire)(unstretched length of wire/incremental change in length). Gauge factor gives information on the expected resistance change or output signal at maximum permissible elongation.the gauge factor DETERMINES to a large extent the sensitivity of the wire when it is made into a practical strain gauge.
