Problem 26.4: Find the dielectric

Please wait for the animation to completely load.

The animation shows a parallel-plate capacitor with a hidden dielectric between the two plates. You can click-drag to measure position and electric potential (position is given in meters and electric potential is given in volts). The small black circle in the center is a dragable test charge that can be used to show the direction and magnitude of the electric field. Click on the add marker links to add a blue or red marker at the location of the test charge to outline the edges of the dielectric. Restart.

  1. Sketch and label an estimate of the location of the dielectric.
  2. Sketch a representative number of equipotential lines.
