The disadvantage with paper as insulating material is____________?
Correct answer: A. it is hygroscopic
- A. it is hygroscopic
- B. it has high capacitance
- C. it is an organic material
- D. none of the above
Explanation
Paper readily absorbs moisture because it is hygroscopic, and absorbed moisture sharply reduces its insulation resistance and dielectric strength. It must therefore be thoroughly dried and protected by a sheath.
