👉 In physics, an antikathode is a type of cathode that is made from a material that is used to shield certain components or devices from electric fields. This type of cathode is typically used in electronic circuits and is designed to protect sensitive components such as resistors, capacitors, and diodes from the effects of electric fields. The antikathode is usually made from a highly conductive material like copper or aluminum, which has a high electrical resistance compared to other materials.
