Verified Answer
For wire wound strain gauges, the gauge factor is defined as-a)1 + vb)...
The gauge factor is defined as the ratio of per unit change in resistance to per unit change in length.
Gauge factor, 
Where ε = strain = ΔL/L
The gauge factor can be written as
= Resistance change due to change of length + Resistance change due to change in area + Resistance change due to piezo resistive effect
If the change in the value of resistivity of a material when strained is neglected, the gauge factor is:
The above equation is valid only when Piezo resistive effect that is change in resistivity due to strain is almost neglected.
For wire wound strain gauges, Piezo resistive effect is almost negligible.
