reverse bias उदाहरण वाक्य

उदाहरण वाक्य

1. MQW devices must be operated at high reverse bias fields to achieve good contrast ratios.
2. In this diode the voltage remains relatively constant ( independent of current ) when it is connected in reverse bias.
3. Under reverse bias, the diode ordinarily does not conduct ( save a small dark current or I s leakage ).
4. When the reverse bias breakdown voltage is exceeded, a conventional diode is subject to high current due to avalanche breakdown.
5. In either formulation, r _ O varies with DC reverse bias V _ { CB }, as is observed in practice.
6. The small current that flows under high reverse bias is then the result of thermal generation of electron-hole pairs in the layer.
7. When this energy level is higher than that of the electrons, no tunnelling will occur, and the diode is in reverse bias.
8. The collector depletion region also increases under reverse bias, more than does that of the base, because the collector is less heavily doped.
9. This depletion region is much larger than in a PN diode, and almost constant-size, independent of the reverse bias applied to the diode.
10. There is also a recovery concern where the current will not decrease immediately when it is switched from forward bias to reverse bias.
