concept of negative resistance in context with scr UNANSWERABLE what is this resistance? In electronics, “Negative Resistance” is a property of some electrical circuits and devices in which an increase in voltage across the device's terminals results in a decrease in electric current through it. what are the different ones? In an electronic device, the differential resistance formula_14, the static resistance formula_15, or both, can be negative, so there are three categories. when was it first discovered? It was first recognized during investigations of electric arcs, which were used for lighting during the 19th century.

Electric arc [SEP] Introduction
An electric arc, or arc discharge, is an electrical breakdown of a gas that produces a prolonged electrical discharge. The current through a normally nonconductive medium such as air produces a plasma; the plasma may produce visible light. An arc discharge is characterized by a lower voltage than a glow discharge and relies on thermionic emission of electrons from the electrodes supporting the arc. An archaic term is voltaic arc, as used in the phrase "voltaic arc lamp". Techniques for arc suppression can be used to reduce the duration or likelihood of arc formation. In the late 1800s, electric arc lighting was in wide use for public lighting.
