The thickness of insulation provided on the conductor depends on_____________?
Correct answer: A. the magnitude of voltage on the conductor
- A. the magnitude of voltage on the conductor
- B. the magnitude of current flowing through it
- C. both A. and (b)
- D. none of the above
Explanation
Insulation thickness is mainly selected to withstand the conductor's voltage and prevent dielectric breakdown. Current chiefly determines the conductor's cross-sectional area and heating capacity, not insulation thickness.
