The electric field across a boundary is discontinuous. Does this mean there is no field at the boundary? Can you explain if there is no electric field there, the work done across the boundary?

  • think of a straight slope on a mountain, then there is a vertical Step and after it the slope ist steeper (or less steep) Is there no work going au over tis disconuiity? – trula Jun 23 '20 at 16:37
  • what about the work between two points both on the vertical step? – 1500kook12 Jun 23 '20 at 16:57

  • If your field is truly discontinuous, then there is no meaning to "at the boundary". But you can figure out what's going on by replacing the discontinuity (unphysical) with a very steep slope (an improvement). – garyp Jun 23 '20 at 17:40
