In the cuircuit shown here the transistor used has a current gain `beta=100`. What should be the bias resistor `R_(BE)` so that `V_(CE)=5V("neglect "V_(BE))`

A

`1 xx 10^(3) Omega`

B

500

C

`200 xx 10^(3) Omega`

D

`2 xx 10^(3) Omega`

Text Solution

Verified by Experts

The correct Answer is:
C
`I_(C)=(V_(C C)-V_(CE))/(R_(C))=(10-5)/(1kOmega)=5mA`
`rArrV_(C C)=I_(B)R_(B)=(I_(C))/(beta)R_(B)`
`rArrR_(B)=(beta.V_(C C))/(I_(C))=(100xx10)/(5mA)=200 kOmega`
