Question
Given $V_{C}=8 \mathrm{~V}$ for the network of Fig. 140, determine:a. $I_{B}$.b. $I_{C}$.c. $\beta$.d. $V_{C E}$
Step 1
Since the base-emitter junction is a diode, we can assume that $V_{BE} \approx 0.7V$. Now, we can use Ohm's law to find $I_B$: $I_B = \frac{V_{BB} - V_{BE}}{R_B} = \frac{10V - 0.7V}{100k\Omega} = 93\mu A$ b. Show more…
