DC POWER SUPPLY: Find the DC authority accoutre associated after a while your workbench. Using the equitable cables, amalgamate the DC authority accoutre to a voltage meter. Be abiding you substitute the meter from measuring oppose to actually meaabiding voltage. Using the controls on the DC Authority accoutre, ordain the output voltage to 5V and to 10V. Notice that you may deficiency to use unanalogous outputs to get the desired 0V-10V rove. Show the professor that you can set the voltage to 10V and 5V. OHMS LAW: Select two resistors from the resistor preference bins. The original resistor must be 1W or 10W. This resistor conquer be used as a “vulgar significance” resistor, named Rs. Then selecteded another resistor, R1, that is after a whilein the rove 1kW § R1 § 50kW. 1. Measure, after a while a Multimeter, the oppose treasures of R1 and Rs. 2. Amalgamate R1 and Rs in order on the breadboard. 3. Now meaabiding the whole order opposition. Does the Rs oppose “really” application the whole resistance? 4. Produce abiding the authority is off to the DC authority accoutre. Then amalgamate the express DC voltage marginal to R1. Then amalgamate the plea (GND) DC voltage marginal to the Rs using a combination of cables and wires. 5. Calculate, using Ohms law, how ample vulgar you forebode to course through R1, if the DC voltage is 5V. Archives this treasure and the equation you used. 6. Enabiding the DC voltage is peaceful 5V. Then meaabiding the voltage counter Rs. Using your archivesed oppose treasure and appraised voltage, weigh the vulgar through R1. Does it pair your calculations in stalk 5? 7. Show your results to the professor and get signoff. 8. Turn off the DC authority accoutre. Potentiometer Part A: Obtain a 10K potentiometer and consummate the forthcoming tasks, original after a while no DC Authority amalgamateed. 1. Meaabiding and archives the whole oppose counter the show. (i.e. the outward marginals). 2. Turn the “knob” on the potentiometer. Does the whole oppose substitute? 3. Meaabiding the oppose betwixt an outward marginal of the potentiometer and the average terminal, as you ordain the “knob”. a. What is the restriction oppose you appraise b. What is the utmost opposition? 4. Ordain the oppose betwixt an outward marginal and the average marginal so it is 5KW. Show your results to the professor and get signoff. 4 Potentiometer Part B: Now, allot 5V DC counter the potentiometer and meaabiding the voltage from the average marginal to the plea laterality of the potentiometer, we conquer wheedle this the output voltage. Answer the forthcoming questions: 1. What is the output voltage if the potentiometer was left at the 5KW pose defined in the antecedent minority? 2. What do you forebode the restriction output voltage to be? What do you forebode the utmost to be? 3. Turn the protuberance and validate your results from the antecedent stalk. 4. Disamalgamate the DC authority accoutre and then meaabiding the output oppose at the summit where your output voltage reaches its restriction. What is the treasure of this opposition? Does this treasure produce significance to you? 3B news Example : Why this is a substantial 3B Report 1) It is not a soon lab news 2) It is short, covers the key culture objectives, is technically constructive, and has the right balance betwixt the three required components (Objectives, Accomplishments, Proximate Steps) Improvements Needed 1) Grammar / Editing 2) Sentence Flow We explored the transistor 2N3904’s three erratic regions. We analyzed how the appraised parameters of junction’s vulgars and voltages on how it affected its singularitys. We computed the beta treasure from the appraised treasures. We uplift a tour capable of alloting changeable voltage counter the BJT’s baseemitter terminals. Our appraised and speculative I-V treasures developed that all three regions of production were amend. Our I-V concoct singularity paired the BJT’s datasheet after a whilein 5%. In figure1, after a while increasing unwandering IB the IC slightly changed after a while VCE, causing the I-V incurvation to had non-zero spring in the erratic region. If the I-V incurvations spring were unabrupt to the left, our existing voltage would be encircling 200. This was a amiable transistor consequently of its broad dc-disadvantage rove region. Our tour exhibited unanalogous beta levels from 180 to 220, thus our tour disadvantage summit was perceptive and subject to the transistor’s beta. The beta governed our tour dilution equitablety. Ideally, we would absence to our tour to be insubject of beta to engender varieties of transistors. With basic BJT understandings, we conquer be adding another BJT station to our audio amplifier sketch to consummate the best output bring-about proximate week. (paint of the appearance)
