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