In a n-p-n transistor circuit, the collector current is 10 mA. If 95 per cent of the electrons emitted reach the collector, which of the following statements are true? |

Answer» The EMITTER current will be 8 mA. `therefore 10=0.95I_(E ) (because (I_(C )=10mA)` `therefore I_(E )=(10)/(0.95)=(1000)/(95)=10.526` `therefore I_(E )~~10.53mA` Here, `I_(B)=5% I_(E )=10.53xx(5)/(100)=0.5265mA` `therefore I_(B) ~~ 0.53mA` |
