Match List I with List II Choose the correct answer from the options given below:LIST I LIST II A. Relative error I. The ability of tde device to give identical O/P when repeated measurements are made witd tde same I/P signal B. Precision II. The ratio of difference between measured value and tde true value to tde true value of tde measurand C. Caliberation III. The smallest increment in measure tdat can be detected witd certainity by tde instrument D. Resolution IV. The process of making adjustments or tde scale so tdat tde instrument reading conform to an accepted standard.
A-II, B-I, C-IV, D-III
To solve this question, we need to accurately match the terms in List I with their corresponding descriptions in List II. Let's analyze each item one by one:
- Relative Error
This is the comparison of the error in a measurement to the true value of the measurement, usually expressed as a percentage. Thus, it aligns with: \(II\): "The ratio of difference between measured value and the true value to the true value of the measurand." - Precision
Precision refers to the consistency of repeated measurements. It describes how close repeated measurements of the same item are to each other. Therefore, it matches: \(I\): "The ability of the device to give identical output when repeated measurements are made with the same input signal." - Calibration
Calibration is the process of adjusting the instrument to ensure its accuracy by comparing it with a standard. Hence, it corresponds to: \(IV\): "The process of making adjustments or the scale so that the instrument reading conforms to an accepted standard." - Resolution
Resolution is the smallest detectable increment that can be measured by an instrument with certainty. Thus, it aligns with: \(III\): "The smallest increment in measure that can be detected with certainty by the instrument."
Based on the above analysis, the correct matches are:
- A (Relative error) - II
- B (Precision) - I
- C (Calibration) - IV
- D (Resolution) - III
Thus, the correct answer is: A-II, B-I, C-IV, D-III.
