Explanation: Strain gage changes resistance when an external stress is applied. Therefore, the stress is defined as force/unit area i.e. Newton / meter^2. 4. Which type of strain gage has better resolution?
A. Semiconductor strain gage
B. Wire strain gage
C. Wire and Semiconductor strain gage
D. None of the mentioned
Answer:A
Explanation: Strain gage changes resistance when an external stress is applied. Therefore, the stress is defined as force/unit area i.e. Newton / meter^2. 4. Which type of strain gage has better resolution?
A. Semiconductor strain gage B. Wire strain gage C. Wire and Semiconductor strain gage D. None of the mentioned
Explanation: Semiconductor strain gage are much more sensitive than wire type and so, it provide better accuracy and resolution. 5. How a differential instrumentation amplifier using transducer bridge can be used as a temperature controller?
