In an electric press mica is used_____________?
Correct answer: A. as an insulator
- A. as an insulator
- B. as a device for power factor improvement
- C. for dielectric heating
- D. for induction heating
Explanation
Mica has high dielectric strength and good heat resistance, so it is used as an electrical insulator in presses and heating equipment. It is not itself a power-factor correction or heating method.
