Circuit Analysis – Week #1 Lab Use the following (also found in Tools and Templates) when submitting your lab work. 1. The lab document must be a Word document. PDF files are NOT accepted. 2. All screenshots must be included. 3. All screenshots must include the Multisim . 4. Any and all Multisim files must be submitted. 5. Calculations must be provided when relevant to show how you arrived at any calculated numbers. 6. Any equations used must be typed in Word. Copy and paste of equations from outside sources is prohibited. 7. No graphics are allowed in the Word document other than screenshots of circuits from Multisim with the time stamp. 8. The lab template must be used. Specifically, it is brought to your attention that a summary MUST be provided explaining the results of the labs, the relationship of the results to expected results, and any challenges encountered. This is a personal reflection on the lab but rather a professional five sentence or more summary of the lab. Any violation of the submission rules above will result in a grade of 1. In preparation for the lab, research what resistance tolerance is and what causes is. Think about the impact resistance tolerance would have on measured values in a circuit. While resistance tolerance means that a given resistance will have a different resistance other than the ideal, it will not fluctuate over a short period of time. Think about these questions before starting the lab as it will you in the analysis: Why then in a physical electrical circuit do the measurements fluctuate? What are the other factors involved? Is there anything else which effects the resistance value when placed in a circuit in a certain location? This week’s lab introduces you to the construction of a resistive network in Multisim and identifying the effect of tolerances. You will learn to utilize Multisim to confirm your calculations. Resistance Tolerance Calculated Vx (V) Measured Vx (V) Measured Vx (V) Measured Vx (V) Average Measured Vx (V) 7KΩ 7KΩ 5% 7KΩ 10% 2. Construct the above circuit in Multisim. If you need with Multisim, refer to the tutorials in the Tools and Templates section. use the following (also found in the Tools and Templates) if you need setting up tolerances in Multisim. Use the Agilent Multimeter to make measurements. 3. Simulation: 4. Analysis: In this section, you are to analyze your results. While the following questions MUST be answered, they may NOT be exhaustive nor represent all that you may want to look at. You may have other items you would like to address or calculate. You may have an idea to expand the table for the analysis to look at an additional item. You are free and expected to do that here as this is a minimum guide. a. Calculate the average measured value for each tolerance level. e. While the simulation mimics changing out the resistor with a new resistor every time you run the simulation, it also reflects some of the variation one might experience with one resistor in a typical operating scenario. Why is that? What things besides tolerance effect the resistance value and measurements in real circuits? Explain at least one of those items in detail from the perspective of physics. 1. The lab document must be a Word document. PDF files are NOT accepted. 2. All screenshots must be included. 3. All Multisim screenshots must include the . See TOOLS AND TEMPLATES for the procedure to display the date and time. 4. Any and all Multisim files must be submitted. 5. Any equations used must be typed in Word. 6. No graphics are allowed in the Word document other than screenshots of circuits from Multisim and hardware if applicable, with the date/time stamp. 7. The lab template should be used. Specifically, it is brought to your attention that a summary MUST be provided explaining the results of the labs, the relationship of the results to expected results, and any challenges encountered. 8. Hardware portion of labs should include screenshots of the assembled circuit with your name and student GID number written on paper next to the circuit. See example below. Any violation of the submission rules above will result in a grade of 1.

Frequently asked questions
Is your service confidential?
When you place an order with our company, we ask you to provide us with such personal information as your name, phone number, and email address. We need this data to keep you updated on the important things related to your order or account.
Is there a possibility of plagiarism in my completed order?
We complete each paper from scratch and in order to make you feel safe regarding its authenticity, we check it for plagiarism before its delivery. To do that, we use our in-house software, which can find not only copy-pasted fragments but even paraphrased pieces of text. Unlike popular plagiarism detection systems that are used by most universities (e.g. Turnitin.com), we do not report to any public databases—therefore, such checking is safe.
We provide a plagiarism-free guarantee that ensures your paper is always checked for its uniqueness.
Is there a money-back guarantee? If yes, how can I receive a refund?
You can certainly get your money back in several cases. You can receive a full refund if you have paid for your order twice or if you have placed two identical orders. In case your paper was late or the quality of the paper does not correspond to your expectations, you will get compensation for these issues.
Do you keep a database of pre-written essays?
No, we do not have such a database. All papers you order from us are written from scratch. This means your paper is unique and has never been published before—neither will it be published after we deliver it to you.
When will my custom paper be done?
While placing an order with WritersHub, you can choose a period of time within which a paper should be delivered to you. The countdown until the specified deadline starts automatically from the moment we receive your payment in our system. For example, if you pay for your order at 6pm on Monday and choose a 3-day delivery option, you will receive your custom paper by 6pm on Thursday.
Remember that a writer needs a sufficient amount of time in order to conduct thorough research. Therefore, please choose the most suitable deadline when you place an order. Moreover, the later you need your paper to be delivered to you, the cheaper it will be. Thus, you will be able to save your money while your writer will have enough time to work on your order and ensure its quality.
Make sure you upload all the additional materials at the very beginning. If you fail to do that, the deadline for your order will be postponed as well.
I haven’t received my custom paper by the deadline. What should I do?
Let us know immediately about that. You can do it by writing a message on Facebook or email us. Our support manager will carefully examine your order and will assist you with it right away. The reasons for late delivery may vary from time to time. It can happen that you have entered a wrong email address or your spam filter does not allow you to receive emails from us. It is also possible that the writer is waiting for your reply and can not continue working without your assistance, or we are checking the work for plagiarism. Whatever the case may be, contact us if you have any problems with getting your order on time.
