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. what is this arc? An electric arc is an electrical breakdown of a gas that produces a prolonged electrical discharge.

Electric arc [SEP] History
Sir Humphry Davy discovered the short-pulse electrical arc in 1800. In 1801, he described the phenomenon in a paper published in William Nicholson's "Journal of Natural Philosophy, Chemistry and the Arts".According to modern science, Davy's description was a spark rather than an arc. In the same year Davy publicly demonstrated the effect, before the Royal Society, by transmitting an electric current through two carbon rods that touched, and then pulling them a short distance apart. The demonstration produced a "feeble" arc, not readily distinguished from a sustained spark, between charcoal points. The Society subscribed for a more powerful battery of 1,000 plates, and in 1808 he demonstrated the large-scale arc.
