  • We know the gain of a BJT transistor given y the formula

$A_v=\dfrac{V_o}{V_i}$

  • Hence the Output Voltage is the product of Gain and Input Voltage

     $V_{o}=300V$

  • Wr know the Stability factor for a BJT transistor is given as

$S=\dfrac{(\beta+1){(1+\dfrac{R_1}{R_L})}}{({\beta+1)}+\dfrac{R_1}{R_L}}$

 

  • From data sheet of BJT147B transistor we have Gain value of …
