66N-type semiconductor — N type semiconductors are a type of extrinsic semiconductor where the dopant atoms are capable of providing extra conduction electrons to the host material (e.g. phosphorus in silicon). This creates an excess of negative (n type) electron charge… …
67Hydraulic analogy — The electronic–hydraulic analogy (derisively referred to as the drain pipe theory by Oliver Heaviside) is the most widely used analogy for electron fluid in a metal conductor. Since electric current is invisible and the processes at play in… …
