The deflection of the free end of the bimetallic strips in a bimetallic thermometer with temperature is nearly__________________?
Correct answer: A. Linear
- A. Linear
- B. Non-linear
- C. Parabolic
- D. Hyperbolic
Explanation
Over its normal operating range, the difference in expansion of the two bonded metals produces a deflection that is approximately proportional to temperature change. Thus the scale is treated as nearly linear, although wide ranges introduce some curvature.
