In an NPN transistor circuit, the collector current is 10mA. If 95 per cent of the electrons emitted reaches the collector, which of the following statements are true? (a) The emitter current will be 8 mA (b) The emitter current will be 10.53 mA (c) The base current will be 0.53 mA (d) The base current will be 2 mA
Ic=10mA Ic=95% of Ie or Ic=10095Ie Ie=9510mA×100=10.53mA Ib+Ic=Ie So Ib=Ie−Ic=10.53−10=0.53mA
