Answer should be resistance.

Keshav said:   7 years ago
Strain gauge output in the form of resistance.

Sudhir kumar said:   7 years ago
If it asks only output of strain gauge then answer should be resistance.

Yes, the right answer is B.

While a strain gauge itself experiences a change in resistance due to applied strain, this change in resistance is typically converted into a voltage signal for amplification and measurement.

This conversion is often achieved using a Wheatstone bridge circuit.

Therefore, the final output quantity that is measured and interpreted is voltage.
