Which of the following is NOT a systematic error?
Model Answer & Options
Source: Extra PracticeZero error in a Vernier calliper
Error due to personal bias of the observer
Error due to change in temperature during the experiment
Error due to random fluctuations in line voltage
Explanation
Systematic errors are those that tend to be in one direction (either positive or negative) and can often be identified and corrected (instrumental errors, personal errors, imperfection in technique). Random errors, however, are those that occur irregularly and are due to random and unpredictable fluctuations in experimental conditions like temperature, voltage, or mechanical vibrations. Therefore, random fluctuations in line voltage are classified as random errors, not systematic errors.
