of 250 and a base current, IB, of 20 
A. The collector current, IC, equals:| Koudinya said: (Oct 19, 2010) | |
| Ic = Beta x Ib | |
| Laxman said: (Dec 3, 2010) | |
| Ic=Beta*Ib Ic=250*20/1000000 =5000/1000000 Ic=5mA |

| Beta=Ic/Ib Ic=Beta*Ib Ic=250*20/1000000 Ic=5mA |

| Beta is 250,Ib=20 collector current Ic=(Ib*beta)/10^6 Ic=5000/10^6 =5mA |

| For dc operation of bjd Ic=Ie+(beta)Ib But for Ib=20ua current value, Ie negligible so considered as zero. => Ic=250*20uA=5mA. (ans) |

| Bdc is 250 and current base Ib=20 so they formula say that collector current(Ic)= Ib*Bdc then IC= 20*250 =5000 sol: 5mA |

| Ic=BIb =250*20*10^-6 5 mA |

| Ic=Beta*Ib =250*20*10^-6 =5*10^-6 =5mA |

| THE FORMULA USED TO FIND OUT THE IC IS Ic = Ib*GAIN = (20*10^-6)*(250) =5*10^3* 10^-6 = 5mA |

| In common emiter configuration, amplification factor is given by BETE=Ic/Ib. Ic=BETA*Ib =250*(20*10^-6) =5000*10^-6 =5mA |

| From formula, Ic(collector current) = Beta*Ib(base current). =250*20*10^-6. =5*10^-3. =5mA. |

| Ic = BIb. Ic = 250*20*10^-6. Ic = 5mA. |

| Given datas:bette = 250,current base = 20micro ampere. Then IC = bette*current base. IC = 250 * 20 = 5000micro ampere. Convetion of 5000MA into mA will be 5mA(Ans). |

| β = Ic/Ib. Ic=betta * Ib. Ic = 250 * 20micro Ampere. Ic = 5mA. |

| Moin Ansari said: (Aug 25, 2018) | |
| As we know that the amplification factor in ce mode β=Ic/Ib. and Ib is in micro range so 20*1000000, 250*20/1000000=5ma answer. |
