Question

In the circuit shown, the value of $\beta$ of the transistor is 48. If the base current supplied $200\mu A$, what is the voltage at the terminal Y?

• A. 0.2 V
• B. 0.5 V
• C. 4 V
• D. 4.8 V

Answer 1

The correct option is A 0.2 V


$\beta =\frac{I_c}{I_b}\Rightarrow I_c=48\times 200\times {10}^{-6}=96\times {10}^{-4}A\therefore V_{cc}-I_c{R}_c=V_y\Rightarrow 5-96\times {10}^{-4}\times 500=V_y\Rightarrow V_y=0.2V$
