For dynamic strain measurement, the Wheatstone bridge used is of ______________ type ?
Correct answer: D. Voltage sensitive deflected
- A. Voltage sensitive null
- B. None of these
- C. Current sensitive deflected
- D. Voltage sensitive deflected
Explanation
Dynamic strain measurement requires a deflection-type Wheatstone bridge, whose output voltage changes with strain and is measured continuously. A null bridge is mainly suited to static or balance measurements.
