In a transistor if ICIE=α and  ICIB=β, if α  varies between  2021 and  100101, then the value  β of lies between

β=α1−α                         β=α1−α =20211−2021                          =1001011−100101 =2021121                                 =1001011101 β=20                                 β=100 ∴β lies between 20 – 100
