WebDoing DC analysis of the transistor circuit is the most common way of finding out the value of I B in the circuit. The equation to solve for I e is: So we must solve for V bb and R B in order to solve for I B. Next we compute the value of R B: Now we can calculate the value of the base current, I B, in the circuit: WebMay 1, 2024 · 3. You know IE = 9.96 mA You know IB = 0.101 mA You know that IC=IE-IB = 9.86 mA You know that B = IC/IB hFe = 97 mA/mA. This is the transistor gain when this value of IB is feed in the base at that particular voltage VCE. In your particular case this value may not be very useful because the circuit puts transistor in saturation. thorne nature https://gospel-plantation.com
