Question

The Piezoelectric effect is generally found in:

• A. Conductors
• B. Insulator
• C. Semi Conductors
• D. Magnetic Material

Hint:

Piezoelectric materials are usually non-centrosymmetric insulating crystals.

Answer 1

The Correct Option is B

Concept:
Piezoelectric effect is the generation of electric polarization or voltage in a material when mechanical stress is applied.

Step 1: Understand piezoelectric materials.
Piezoelectric materials are usually non-centrosymmetric dielectric materials.

Step 2: Identify the general category.
Dielectric materials are generally insulators. \[ \text{Piezoelectric effect} \rightarrow \text{Insulating crystals} \]

Step 3: Final conclusion.
Therefore, the piezoelectric effect is generally found in insulators. \[ \therefore \text{Correct Answer is (B)} \]
