# ECET220 Week 2 Homework

of 1

Chapter 3 Homework Questions 1.What is the exact value of IC for IE= 5.54 mA and IB= 47.5 µA 5. Determine the IB, IC, and VC for the transistor circuit in Figure 3-66. Assume βDC= 75. 6. Draw the dc load line for the transistor circuit in Figure 3-67. 9. Repeat Problem 8 for βDC= 300. (Hint: The transistor is now saturated!) (8. For the base-biased npn transistor in Figure 3-68, assume βDC= 100. Find IC and VCE.) 13. For the voltage-divider biased circuit in Figure 3-71, determine IC and VCE.
