અને \( I_C = I_E\) ના \(90\%\) ઇલેક્ટ્રોન થી મળતો પ્રવાહ , 

\(\therefore \,\,{I_C} = \,\,\frac{{{I_E} \times \,\,90}}{{100}}\,\,\,\,\,\,\,\,\,\therefore \,\,\frac{{{I_C}}}{{{I_E}}}\,\, = \,\,\,0.9\,\,\,\,\,\,\therefore \,\,\alpha \,\, = \,\,0.9\,\,\,\,\left( {\because \,\,\,\frac{{{I_C}}}{{{I_E}}}\,\, = \,\,\alpha } \right)\)

અને \(\beta \,\, = \,\, \frac{\alpha }{{1 - \alpha }}\,\,\,\, = \,\,\,\frac{{0.9}}{{1 - 0.9}}\,\,\,\, = \,\,\,\frac{{0.9}}{{0.1}}\,\,\, = \,\,9.0\)
