### Explanation of question 16

A thermocouple instrument has

1. a linear scale
2. a quick response
3. a low overload capacity
4. 1, 2 and 3

The answer is :- 3 The scale on a thermocouple instrument is not linear (heating effect is proportional to I2). Since its action depends upon the temperature change of a wire, it is sluggish in response. The fine wire is easily fused so that the instrument has a low overload capacity.
