Dear Student,

current amplification factor, α=0 95Ib=0
2 mAcurrent gain for common base circuit is, α=IcIe0
95=IcIeor, Ic=0 95×IeAlso, Ie=Ib+IcIe=0 2+0
95×IeIe-0 95×Ie=0 2Ie=0 20 05=4 mA

In common base circuit of a transistor, current amplification factor is 0.95. Calculate the emitter current if base current is 0.2 mA (A) 2 mA (B) 4 mA (C) 6 mA (D) 8 Ma
