An N-P-N transistor in a common emitter mode is used as a simple voltage amplifier with a collecter current of 4mA. The terminal of a 8 V battery is connected to the collector through a load ressitance `R_(L)` and to the base through a resistance `R_(B)`. The collector-emitter voltage `V_(C E ) =4V` base -emitter voltage
`V_(BE) = 0.6V` and base current amplification factor `beta_(d.c.) = 100`.Find the values of `R_(L)` and `R_(B)`.

Options

A. `R_(L)=1k Omega , R_(B) = 185 kOmega`
B. `R_(L) = 2kOmega , R_(B) =150 k Omega `
C. `R_(L) = 1 k Omega ,R_(B) =240 kOmega `
D. `R_(L) = 3k Omega , R_(B )=185 kOmega`

Answer

A
