The errors in the measurement which arise due to unpredictable fluctuations in temperature and voltage supply are:

Options

  1. ARandom errors
  2. BInstrumental errors
  3. CPersonal errors
  4. DLeast count errors

Correct answer

A. Random errors

Step-by-step solution

The errors which cannot be associated with any systematic or constant cause are called random errors. These errors can arise due to unpredictable fluctuations in experimental conditions, e.g., random change in pressure, temperature, voltage supply etc. An example of random error is putting the same weight on an electronic scales several times and obtaining readings that vary in random fashion from one reading to the next.
