Which of the following comes under the category of random errors?

Options

  1. AImproper calibration of thermometer
  2. BZero error of 1 V in voltmeter
  3. CStudent measures 22^ , where as the correct angle is 20^
  4. DErrors resulting from the fluctuations in electric power supply

Correct answer

D. Errors resulting from the fluctuations in electric power supply

Step-by-step solution

Random errors occur irregularly with random magnitude and direction, arising from unpredictable fluctuations in experimental conditions or personal judgment. Systematic errors produce consistent deviations, as seen with improper thermometer calibration and voltmeter zero error where measurements are predictably biased. The described angular measurement deviation lacks context to definitively classify as either systematic or random. Fluctuations in electric power supply cause unpredictable instrument variations, pro
