Which of the following is not a quality of a non-metallic mineral called Mica?
- A.
It splits into thin sheets
- B.
It has dielectric strength
- C.
It is not resistant to high voltage
- D.
It has low power loss factor
Attempted by 163 students.
Show answer & explanation
Correct answer: C
Answer: The statement "It is not resistant to high voltage" is not a quality of mica.
Why:
Mica splits into thin elastic sheets due to perfect basal cleavage.
Mica has high dielectric strength and resists high voltage, which is why it is used as an electrical insulator and in capacitors.
Mica has a low power loss factor (low dielectric loss), making it suitable for high-frequency and low-loss electrical applications.
Conclusion: Because mica resists high voltage and has high dielectric strength, the claim that it is not resistant to high voltage is false. Therefore that claim is the correct choice for the question asking which statement is not a quality of mica.
