\(\because \,\,\beta \,\, = \,\,\frac{{{I_c}}}{{{I_b}}}\,\,\,\therefore \,\,\,{I_c}\,\,\, = \,\,\beta \,{I_b}\,\, = \,\,50\,\,{I_{b\,}}.........\left( i \right)\)

\({I_c}\,\, = \,\,\,{I_c}\, + \,\,{I_b}\) સમી. નો ઉપયોગ કરતાં \(\,6.6 = 50\,\,{I_b}\,\,\, + \;\,{I_{b\,}} = 51\,\,{I_b}\)

\( \Rightarrow  {I_b}\,\, = \,\,\frac{{6.6}}{{51}}\,\, = \,\,0.129\,\,mA\)

આમ, \({I_c}\,\, = \,\,50\,\, \times \,\,\frac{{6.6}}{{51}}\,\,mA\) અને \(\alpha \,\, = \,\,\frac{\beta }{{1\,\, + \;\,\beta }}\,\, = \,\,\frac{{50}}{{51}}\,\, = \,\,0.98\)
