WebNow, double the collector current and find that V B E = 0.708 V Increasing the collector current 100% only increased the base-emitter voltage 2.45% So, while it is not true that the base-emitter voltage is constant, it is not a bad approximation to consider it constant over a relatively wide range of collector current. Share Cite Follow WebWhat is beta DC in transistors? Typically, Beta has a value between 20 and 200 for most general purpose transistors. So if a transistor has a Beta value of say 100, then one electron will flow from the base terminal for every 100 electrons flowing between the emitter-collector terminal. sidewinder precision pro software windows 7WebGenerally no arrow head is marked for collector since its reverse leakage current is always opposite to the direction of emitter current. 4. Discuss the need for biasing the transistor. For normal operation, base-emitter junction should be forward biased and the collector-base junction reverse biased. the point garden city sc

"WebApr 15, 2011 · A transistor goes into saturation when both the base-emitter and base-collector junctions are forward biased, basically. So if the collector voltage drops below the base voltage, and the emitter voltage is below the base voltage, then the transistor is in saturation. Consider this Common Emitter Amplifier circuit.
