Question

At the planar interface of two dielectrics, which of the following statements related to the electric field (\(\vec{𝐸}\) ), electric displacement (\(\vec{D}\)) and polarization (\(\vec{P}\) ) is true ?

• A. Normal component of both \(\vec{𝐷}\) and \(\vec{𝑃}\) are continuous
• B. Normal component of both \(\vec{𝐷}\) and \(\vec{E}\) are discontinuous
• C. Normal component of \(\vec{D}\) is continuous and that of \(\vec{𝑃}\) is discontinuous
• D. Normal component of both \(\vec{𝐸}\) and \(\vec{𝑃}\) are continuous

Answer 1

The Correct Option is B

The correct option is (B) : Normal component of both \(\vec{𝐷}\) and \(\vec{E}\) are discontinuous.
