Question

Sensitivity of an instrument is defined as

• A. Accuracy
• B. Reciprocal of resolution
• C. Ability to measure large signals
• D. Output per unit input

Hint:

Higher sensitivity means \[ \boxed{ \text{A small change in input produces a larger change in output.} } \]

Answer 1

The Correct Option is D

Step 1: Recall the definition of sensitivity. Sensitivity is the ratio of the change in output to the corresponding change in input. Mathematically, \[ \boxed{ \text{Sensitivity} = \frac{\Delta \text{Output}}{\Delta \text{Input}} } \]

Step 2: Identify the correct option. Since sensitivity represents output produced for each unit of input, \[ \boxed{\text{Output per unit input}} \] is the correct answer. Therefore, \[ \boxed{(D)} \] is the correct answer.
