When a dielectric is placed in an electric field the field strength____________?
Correct answer: A. decreases
- A. decreases
- B. increases
- C. reduces to zero
- D. remain unchanged
Explanation
A dielectric polarizes when placed in an electric field, producing an opposing field. For a linear dielectric, the resulting field is E = E₀/εᵣ, so its strength decreases rather than becoming zero.
