An n-p-n transistor in a common emitter mode is used as a simple voltage amplifier with a collector connected to load resistance `R_(L)` and to the base through a resistance `R_(B)`. The collector-emmiter voltage `V_(CE) = 4V`, the base-emitter voltage `V_(BE) = 0.6 V`, current through collector is `4 mA` and the current amplification factor `beta = 100` Calculate the value of `R_(L)` and `R_(B)`.
