For a transistor connected in common emitter mode , the voltage drop across the collector is 2 V and beta is 50 . Find base current if R_(C) is 2K . |

Answer» SOLUTION :DATA SUPPLIED , `V_(CE) = 2V , beta = 50` `R_(C) = 2 K = 2 xx 10^(3) Omega` `I_(C) = (V_(CE))/(R_(C)) = (2)/(2 xx 10^(3)) = 1 mA` `beta = (I_(C))/(I_(B))` `I_(B) = (I_(C))/(beta) = (10^(-3))/(50) = 20 MU A` |
