Question

Quizplus · Accepted Answer

In electronics, the three primary categories of materials are semiconductors, insulators, and conductors. Crystals, while important in electronics for various applications (e.g., quartz crystals in oscillators), are not categorized as a primary material type like the other three. Crystals can be made of semiconductors, insulators, or conductors, depending on their atomic structure and composition.
