Problem 4: A BJT is as shown in Figure 4 is specified to have BF in the range of 8 to 40. The load resistance is Rc=12.0 ohms, The DC supply voltage Vcc= 200V and the input voltage to the base circuit is VB=10V, the saturation collector emitter voltage VCESAT =1.0V and the saturation base emitter voltage VBESAT=1.5V. Find RB, B forced and Power loss (PT) in the transistor for ODF range=1 to 12 increments of 0.5. Note. Show your computation for each case and summarize all results in a tabular form. Plot ODF versus PT.
