سوالات تشریحی
16-Translate the following texts into fluent Persian: The basic operation of the light-emitting Y.YY sy. diode(LED) is as follows.when the device is forward-biased, electrons cross the pn junction from the n-type material and recombine with holes in the p-type material.These free electrons are in the conduction band and at higher energy than the holes in the valance band.when recombination takes place,the recombination electrons release
17-To illustrate transistor action,let's examine what happens inside the npn transistor.The ۲ ،۳۳ نمره forward bias from base to emitter narrows the BE depletion region, and the reverse bias from base to collector widens the BC depletion region.The heavily doped n-type emitter region is teeming with conduction-band(free) electrons.
18-The biasing of a transistor is purely a dc operation.The purpose of biasing is to establish a ۲ ،۳۴ نمره O-point about which variations in current and voltage can occure in response to an ac input signal. In application where small signal voltage must be amplified variations about the O-point are relatively small.
