- Piezoelectric effect
- Hall effect
- Change in resistance due to strain
- Change in capacitance
Show Solution

The Correct Option is C
Solution and Explanation
Step 1: Recall the working principle of a strain gauge.
When a strain gauge is stretched or compressed, its electrical resistance changes.
Step 2: Identify the operating principle. The applied force produces strain, which changes the resistance of the strain gauge. Thus, \[ \boxed{\text{Force measurement is based on the change in resistance due to strain.}} \] Hence, \[ \boxed{(C)} \] is the correct answer.
