In the circuit shown in Fig, the transistor used has a current gain beta=100. If the bias resistance R_(B)=axx10^(5)Omega, then V_(CE)=5 V. Neglecting V_(BE), find the integer value of a?

Answer»


Solution :REFER Fig.applying Kirchhoff's SECOND law to CLOSED circuit `ADCEGA`, we have
`-V_(C C)+I_(C)xx10^(3)+V_(CE)=0`
or `V_(C C)=I_(C)xx10^(3)+V_(CE)`
