The smallest change in a measured variable to which an instrument will...
Explanation:
In electrical engineering, instruments are used to measure different physical quantities such as voltage, current, resistance, temperature, etc. Instruments have different characteristics that define their performance. One of these characteristics is the resolution of the instrument.
What is Resolution?
Resolution is the smallest change in a measured variable to which an instrument will respond. For example, if we have a voltmeter with a resolution of 0.1 V, then the smallest change in voltage that it can measure is 0.1 V. If the voltage changes by less than 0.1 V, then the instrument will not be able to detect the change.
Accuracy vs Precision vs Sensitivity
Accuracy is the degree to which an instrument measures the true value of a quantity. Precision is the degree to which repeated measurements of a quantity give the same result. Sensitivity is the degree to which an instrument responds to small changes in a measured variable.
While accuracy and precision are important characteristics of an instrument, resolution is also important because it determines the smallest change that can be detected by the instrument.
Conclusion
In conclusion, the smallest change in a measured variable to which an instrument will respond is called resolution. It is an important characteristic of an instrument because it determines the smallest change that can be detected by the instrument.
