Unformatted text preview: Final Exam Electronics I 16.365 Name:__________________________ Campus: Lowell / Boston (Circle one) This exam will last three hours. The answers are multiple choice. Please circle the correct answer. If you change your mind, cross out the answer you circled and circle the new answer. Ambiguously circled answers will not be scored. Each problem is worth an equal number of points, which will be scaled such that 35 correct answers=100 points. The following conditions apply to the next three (3) problems: Given the circuit to the right, R C =1k Ω , R B =1k Ω , β =100, V CC =+5V, and v i =+5V 1. What is the base current? a. 4.3 mA b. 4.9 mA c. 6.0 mA d. 10.5 mA e. 11.4 mA 2. What is the collector current? a. 0.028 mA b. 0.032 mA c. 0.61 mA d. 0.67 mA e. 4.8 mA 3. What value of R B is necessary to bring the BJT to the edge of saturation? a. 7.78 k Ω b. 70.7 k Ω c. 91.5 k Ω d. 103 k Ω e. 131 k Ω 4. Find the value of β for this BJT. a. 56 b. 76 c. 90 d. 99 e. 144 The following conditions apply to the next three (3) problems: Consider the circuit to the right with V CC =+5V, R C =5k Ω , and I S =10-15 A 5. What is the theoretical maximum voltage gain this amplifier can provide?...
