Web19 de ago. de 2013 · Using the mean value of 200 gives a nominal base current of 6mA / 200 = 30μA. The total current through R2 when the transistor is ON is thus 8.75μA + 30μA = 38.8μA. We now calculate the value of R2 as (5V - 0.7V) / 38.8μA = 110.8kΩ. This is close to the value of 100k you experimentally determined. Web15 de dez. de 2024 · The transistor stops working as a transistor once it enters saturation. In saturation you can connecta wire from C to E with minimal difference (say use a 0.1 or 0.2V source or whatever. to model small Vsat drop) At that stage it dos not matter if you put more voltage on the base - it has no effect. candlewood media
