Introduction
The Lichtenberg figure is a figure that looks like lightning or tree branches. This happens by giving high-voltage electrical energy. By just using the electrical insulating materials, Lichtenberg figure.
History
Lichtenberg came from the founder of this lightning figure: Georg Christoph Lichtenberg. He was a German physicist and founded in 1777. He reported his findings through the book “Concerning the New Method of Investigating the Nature and movement of Electric fluid”. He made it to show to his students and peers. He used the mixtures of finely-powdered sulfur and red lead dust to observe the patterns after he inserted the electricity into the plates of resin, glass, and hard rubber. He observed that sulfur dust strongly attracts the positively charged region and the red lead dust attracts the negatively charged region.
Mechanism
Specifically, in order to make the Lichtenberg figure, A sharp metal point should be placed and zap the metal object with the electricity on the good electrical conductor plate. It should be zapped, so the electricity travels through the metal and the plate. The longer plate and electricity contacts, the more branches make. After this step, using the powder can reveal the figure. These patterns happen because when the electricity gets absorbed in the plate, the electrons are trapped by the plate and as they exceed the strength of the plate it creates those beautiful branches.
