Explanation: Thermistors are most commonly used because they are relatively easy to mount. 3. What is the unit of strain gage?
A. Ω/oC B. Lux C. Newton / meter^2 D. Volts
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?
