Solid state Guide, Meaning , Facts, Information and Description
In physics, the solid state is one of the three phases of matter (solid, liquid, and gas). See also: solid state physics.In electronics, solid state circuits are those that do not contain vacuum tubes. The term was introduced to describe the transition from valve-based amplifiers to transistorised amplifiers. Solid-state components last much longer than their thermionic counterparts because of their greater resistance to shock, vibration and mechanical wear.
