Cathode Ray Tube (CRT)
A cathode ray tube (CRT) is a device that produces cathode rays (a stream of electrons). The inside of the tube is evacuated or filled with a noble gas. When a high voltage is applied to … more

Electric field line Electric field lines are a visual representation of the electric field around an electric charge. In the case of a point charge, it can be expressed in spreading around the charge. The denser … more
This simulation assumes that the loading dye is 50bp and the marker is 50bp. (‘bp’ is a unit showing the number of base pairs of DNA.) Electrophoresis Electrophoresis is a chemical phenomenon in which an electric … more
Polarizers are made of long-chained molecules which absorb light with electric fields. When you shine a light on a polarizer, only a part of the light is passed. The polarizing plate materials absorb only the electric … more
