Updates to Article Attributes
Body
was changed:
Space charge refers to the collection of electrons which are emitted from the metal surface after,after the application of tube current, at a short distance away from the metal surface.
These electrons collect and form a cloud of charge around the metal surface. This space charge limits the further emission of electrons form the surface and is referred to as space charge effect.
