(1) Thus the outward rectifier does not contribute to the resting conductance.(2) Electric current, on the other hand, can be restricted to one-way flow, as in a rectifier or diode.(3) Our rectifiers have software controls, and we use 30% fewer components because of our software base.(4) Examples include self-winding wristwatches and rectifiers in electrical circuits.(5) Probably the best known use of silicon is in transistors, photovoltaic cells, rectifiers , and other electronic devices.
