માટે \(CE\) માટે પ્રવાહ ગેઇન  \(\,\beta \,\, = \, \frac{\alpha }{{1 - \alpha }}\,\,\, = \,\,\frac{{0.8}}{{1.0 - 0.8}}\,\,\, = \,\,\frac{{0.8}}{{0.2}}\,\,\, = \,\,4\)

હવે, \(\beta \,\, = \,\, \frac{{\Delta \,{I_C}}}{{\Delta \,{I_B}}}\,\,\,\,\,\therefore \,\,\Delta \,\,{I_C} = \,\,\beta \,\, \times \,\,\Delta \,{I_B}\)

પણ \(\Delta \,{I_B} = \,\,6\,mA\,\, = \,\,6\,\, \times \,\,{10^{ - 3}}\,A\) છે. 

\(\therefore \,\,\,\Delta \,{I_C} = \,\,4\,\, \times \,\,6\,\,\, \times \,{10^{ - 3}}\,A\,\,\, = \,\,24\,\, \times \,\,{10^{ - 3}}\,A\,\,\,\, = \,\,24\,\,mA\)
