real-time embedded kernals problem

2. Design the following transistor switch circuit. Interface an LED that requires a forward current ID=15mA. Assume that the forward voltage drop for the LED, VF=2V. A digital output high on the microcontroller turns on the LED, i.e. positive logic. Calculate RB and RC. What is the expected power dissipation in the transistor? Assume Vcc=+5V and VCE(SAI)=0.2V.
