Ceramic is mainly used in the production of high-voltage electrical components because it:

• A. conducts heat
• B. acts as an insulator
• C. conducts electricity
• D. withstands extreme weather

Answer: (B)

High-voltage components need materials that stop current from leaking or arcing. Ceramics provide this by acting as insulators: they have very high electrical resistance and strong dielectric strength, so they resist breakdown under strong electric fields and prevent leakage currents. This insulating capability is why ceramics are used for high-voltage insulation. The other properties—conducting heat, conducting electricity, or just weather resistance—don’t define the essential function here, and ceramics do not conduct electricity. Weather resistance helps in outdoor parts, but the primary reason for their use is their insulating behavior.
