Electric Field Apparatus

A simple model for demonstrating electric fields between various electrode configurations. Place liquid paraffin in the 90 mm petri dish and sprinkle semolina or fine grass seed (not supplied) on the surface. Apply a high voltage via the 4mm terminals and the field pattern is generated. The clear acrylic base allows the pattern to be projected via an overhead projector. (150 x 150 x 60). Note: This apparatus requires a safe, low-current limited 0-5 kV EHT supply.
