Answer:

Explanation:

β =  α / 1-α

β = 99

On applyng voltage law,

( Ic + Ib ) 1 × 10 ³ + 10 ×10 ³ Ib + V Be + I E  × 1 ×10³ = 12

I E = IC +IB

IC +IB ×1 ×10 ³+ 10 ×10 ³ Ib + V Be +IC +IB   × 1 ×10³ = 12

2 (IC +IB )  ×1 ×10 ³+ 10 ×10 ³ Ib + V Be = 12

Ic + 6 IB = 11.2 / 2 ×10³

IB = Ic /β

Ic + 6 Ic /β =  11.2 / 2 ×10³

Ic = 5.33 m A
