The component of the electric field that is always continuous across a dielectric boundary is

  • A.the tangential component of \( \mathbf{E} \)
  • B.the tangential component of \( \mathbf{D} \)
  • C.the normal component of \( \mathbf{E} \)
  • D.the magnitude of \( \mathbf{E} \)

Answer: A

Taking the line integral of E round a thin rectangle straddling the boundary and shrinking it gives equal tangential components, since the static field is conservative. The tangential flux density is correspondingly discontinuous.
