Electrical Engineering XYZ MCQs
Systematic errors are:
- Observational errors
- Instrument errors
- Environmental errors
- All of the above
Correct answer: 4. All of the above
Explanation: Systematic errors are consistent, repeatable errors associated with faulty equipment, incorrect calibration, or biased methodologies that can affect the accuracy of measurements across an entire experiment. Observational errors can occur when measurements are affected by human biases or misinterpretation of instruments. Instrument errors are due to imperfections or persistent malfunctions in the measuring devices. Environmental errors are caused by external conditions affecting the experimental outcomes (like temperature, humidity, etc.). Each of these error types can lead systematically to deviations from true values, hence, all options listed contribute to systematic errors.
