Electrostatic Field Lines (unlike charges)
The electrostatic field lines around a point charge and a plate.The electric field is shown by placing the two plates below a pan filled with cooking oil and pepper flakes. The pepper flakes align in the electric field and allow visualization of the field. In this image the left point is charged to -30,000 volts while the right plate has a potential of + 30,000 volts. This image is part of a series showing different charging conditions.
