Question 194Electricity & Electronics - 1st Asst/Chief

The correct answer is D) electrical insulator. A 'dielectric' is a material that is an electrical insulator or nonconductor of electric current. Dielectric materials have very high resistance to the flow of electric current, and they are used to insulate and separate electrical conductors without allowing current to pass between them. This makes them essential components in various electrical and electronic devices. The other answer choices are incorrect because: A) a good conductor allows current to flow, B) current flow is the movement of electric charge, and C) a semiconductor material is neither a good conductor nor a good insulator.
