Dont approximate. VCC= 6V VEE= -6V Beta = 75 RE = 3.3kOhms, RB = 11kOhms, RC = 1.2kOhms Find the following voltages with respect to ground. VB = Answer 1 Question 1V VC = Answer 2 Question 1V VE = Answer 3 Question 1V To what value can RE be reduced without the transistor going into saturation? Min RE = Answer 4 Question 1Ω As you know, as temperature changes so do BDC and VBE. For the purpose of this question, neglect the change in BDC and only consider the change in VBE. If the transistor used, has a VBE of 0.7V at 25°C and VBE decreases 2.5mV with every degree change in temperature. Find IE if the temperature changes from 25°C to 100°C Use the detailed method for IE IE at 25°C= Answer 5 Question 1mA IE at 100°C= Answer 6 Question 1mA In this problem, you neglected changes in BDC due to temperature. Consider your calculations to determine if the following statement is true or false. The change in BDC, due to temperature, can be neglected when RE is much less than (RB/BDC) Multiple choice 1 Question 1 True False Answer all questions in the unit provided rounded to 2 decimal places.

14. A research and development lab has just built a prototype for a potato peeler. It has many moving parts, but one particular part, the blade patroler, is not supposed to move. When the researchers turn on the machine, they notice that this piece vibrates a little at first, then more, until it is flopping around uselessly. If resonance is responsible for this phenomenon, what can you conclude? Consider the following statements. I. There is a weak connection between this vibration and another vibration. II. There is a strong connection between this vibration and another vibration. III. The two vibrations have similar or equal frequencies. A. II only.. B. I and III. C. II and III D. I or II is true, and III is true

Texts: An enzyme is involved in a dangerous disease and is found at a total concentration of [E]tot = 1.52 mol/L within cells. A known drug D binds 83% of the enzyme E into an inactive complex ED when applied with a total concentration of [D]tot = 2.63 mol/L. The experiments used to determine this data have been performed at a temperature of 37.0°C. Part a) What percentage of the enzyme E is not bound to the drug D under the given experimental conditions? Part b) What total concentration of the drug D is required to bind 95% of the enzyme E under otherwise identical conditions? Part c) An important research goal is to develop a new drug D2, which can bind 95% of the enzyme E at a total concentration of [D]tot = 1.50 mol/L at 37.0°C. Determine the necessary standard. Solve this problem on paper, document your approach, and provide intermediate results. Report the final answers with 3 significant figures. Scan the page(s) and upload them for grading.
