In a transistor circuit shown here the base current is `35 muA`. The value of the resistor `R_(b)` is

A

`123.5 k Omega`

B

`257 k Omega`

C

`380.05 k Omega`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
`R_(B)=(V_(BB)-V_(BE))/(I_(B))`
`=(9)/(35xx10^(-6))=257kOmega` [ Here, `V_(BE)=0` ]
