Electrical Engineering XYZ MCQs
Resolution of an instrument is defined as:
- The maximum nonlinearity
- Ability to distinguish polarity
- Smallest change in value that the instrument can detect or display
- None of above
Correct answer: 3. Smallest change in value that the instrument can detect or display
Explanation: Resolution of an instrument refers to the smallest change in the quantity being measured that the instrument can detect or display. It indicates the precision of the instrument and is important for obtaining accurate measurements. The other options do not accurately describe resolution:
- The maximum nonlinearity is not related to resolution; nonlinearity refers to the deviation of an instrument’s response from a straight line.
- Ability to distinguish polarity is not a common definition of resolution; polarity generally relates to the direction of a quantity, and resolution is more about the smallest change in magnitude that can be detected.
