A silicon transistor amplifier circuit is given below. $(\beta =100)$ . Find collector – emitter voltage

Applying Kirchhoff’s loop rule for base emitter circuit.

$$\begin{gathered} 5-I_B{R}_1-V_{barrier}=0 \\ \Rightarrow I_B{R}_1=5-0.7 \end{gathered}$$

$\Rightarrow I_B=\frac{4.3}{8.6\times {10}^3} = 0.5 mA$

$$\begin{gathered} Also, current gain \\ \beta =\frac{I_C}{I_B} \end{gathered}$$

$\Rightarrow I_C=\beta I_B=50mA$

Applying Kirchhoff’s loop rule for collector-emitter circuit

$I_C{R}_2-10+V_{CE}=0$

$\hspace{0.17em}\hspace{0.17em}\hspace{0.17em}\hspace{0.17em}\hspace{0.17em}\hspace{0.17em}\Rightarrow V_{CE}=10-I_C{R}_2$

$=10-50\times {10}^{-3}\times 100= 5V$
