Description : Define α & β and derive the relation between (α) &) (β) of transistor.
Last Answer : α : The ratio of output collector current IC to input emitter current IE in the CB configuration is called current gain alpha (α). β : The ratio of output collector current IC to the input base current IB in the CE configuration is ... ( 1/β) + 1 hence 1/ α = (1+β )/ β Therefore, α = β /(1+β)
