Some questions involve taking a picture and putting it in the document.
If you don't have a lab kit: for now do it using this simulation (Links to an external site.).
Show your work for each answer where you do a calculation. (include the equation and the values & units for each quantity)

<strong>PART I: Resistors</strong>
Take out the components from your lab kit.
Remember the things we learned in the Lab Intro:
Ohm's Law: ?=??V=IR.
Resistors in Series: ???=?1+?2+...Req=R1+R2+...
Resistors in Parallel: 1???=1?1+1?2+...1Req=1R1+1R2+...
?? What is the voltage of your battery? (measure it)
?? To make sure you don't break the multimeter we're going to calculate the minimum resistance that we can connect to the battery. If you want a maximum possible current of 150 mA, what is the smallest resistance you can attach to your battery?
Make sure that the equivalent resistance you attach to your battery is always at least the value you found in the last question.
Choose any two identical resistors.
??Measure their resistances (they should be about the same). What are they?
Put the two identical resistors in series (NO BATTERY yet) like this:
??What is the predicted value of the equivalent resistance(??Rp)?
??What is the actual equivalent resistance you measure(??Re)?
??Calculate the percent error of the measure value from the predicted value:
%?????=???????????×100%error=|Re?Rp|Rp×100.
Choose any two different resistors (but not TOO different)
??Measure their resistances. What are they?
Put the two resistors in series (NO BATTERY yet) like this:
??What is the predicted value of the equivalent resistance(??Rp)?
??What is the actual equivalent resistance you measure(??Re)?
??Calculate the percent error of the measure value from the predicted value.
Choose any two identical resistors.
??Measure their resistances. What are they?
Put the two resistors in parallel (NO BATTERY yet) like this:
??What is the predicted value of the equivalent resistance(??Rp)?
??What is the actual equivalent resistance you measure(??Re)?
??Calculate the percent error of the measure value from the predicted value:.

Put the two resistors in parallel (NO BATTERY yet) like this:
??What is the predicted value of the equivalent resistance(??Rp)?
??What is the actual equivalent resistance you measure(??Re)?
??Calculate the percent error of the measure value from the predicted value.
??Call in the instructor (aka His Illustriousness Sébastien of House Cormier) to check your work
<strong>PART II: Simple Resistor Circuit</strong>
?? Create Circuit 1 (shown below) using a 20 ohm resistor, your battery, the switch (leave the switch open), and the Ammeter (which is the multimeter set up to measure current). Take a picture of your physical circuit setup and include it here.
NOTE: Always check the values of resistors before putting them in the circuit using the Multimeter in Ohmmeter mode.
?? Circuit 1
?? What is the expected current in this circuit based on Ohm's Law?
?? What is the actual current when you close the switch? (don't forget to open the switch after you measure)
?? Move the Ammeter in the circuit so that is between the switch and the resistor. What is the current now (when the switch is closed)?
?? How do the answers of #6 and #7 compare? Are the answers consistent with your understanding of current?
Remove the Ammeter and rebuild the circuit as shown below
?? Circuit 1 (without the Ammeter)
?? Change the multimeter to Voltmeter mode (using the 2000 mV range). Close the switch. What is the voltageacross (i) the battery, (ii) the switch), and (iii) the resistor? NOTE: Remember the battery voltage is positive and theother ones are negative or zero .
?? What does the sum of the voltages add up to? Is it as expected? Explain.
Open the switch
<strong>PART III: 2 Resistor Series Circuit</strong>
??Set up Circuit 2 (2 resistors in series) shown below using a 100 ohm resistor and a 20 ohm resistor. (in all cases, if you don't have the required resistors use the closest resistors you have. Take a picture of your physical circuit setup and include it here.
?? Circuit 2
?? Calculate the expected equivalent resistance of this circuit.
?? Measure the actual equivalent resistance of this circuit. (make sure the switch is off for this part)
?? What do you expect the current to be (i) through the battery, (ii) between the resistors?
?? Measure the current at those two points. Is it as expected?
?? What do you expect the voltage drop across each resistor to be? Explain.
?? Measure the voltage across each resistor. Is it as expected?
Open the switch
<strong>PART IV: 2 Resistor Parallel Circuit</strong>
??Set up Circuit 2 shown below using a 100 ohm resistor and a 20 ohm resistor. This is 2 resistors in parallel. Take a picture of your physical circuit setup and include it here
?? Circuit 3
?? Calculate the expected equivalent resistance of this circuit.
?? Measure the actual equivalent resistance of this circuit. (make sure the switch is off for this part)
?? What do you expect the current to be through (i) the battery, (ii) the 100 ohm resistor (iii) the 20 ohm resistor?
?? Measure the current at those three points. Is it as expected?
?? What do you expect the voltage drop across each resistor to be? Explain.
?? Measure the voltage across each resistor. Is it as expected?
Open the switch
<strong>PART V: Equivalent resistance of a 4 Resistor Circuit</strong>
We're just using resistors and wires for this one: Make up your own circuit using 4 resistors (make sure to choose 4 resistors that aren't too different from each other and don't just put them all in series! )
?? Draw a circuit diagram. Include a picture of your circuit diagram here.
?? Calculate the expected equivalent resistance of this circuit. (using resistor addition formulas)
?? Measure the actual equivalent resistance of this circuuit.
If you don't have a lab kit: for now do it using this simulation (Links to an external site.).

SCI 110 Confidentiality Ethical Dilemma Case Study Analysis
Read the situation below. Post your own opinion and response to the question on the discussion board.
To get full credit for this assignment:
You should submit an initial contribution with your own analysis and opinion.
Initial posts must include evidence from readings to support your reasoning. 2 pieces of evidence are required. Thoughtful and detailed discussions will earn the most points.
Here is the situation:Dr. Howard Johnson is a tenured Associate Professor in the biochemistry department at a public university. He has been collaborating with a large, multinational pharmaceutical firm for the past six years. During this time the company has supported his research to the extent that they are the sole source of his funding. The research is widely respected and he receives multiple requests each year for seminars, review articles, etc. He anticipates that his promotion credentials for Full Professor will be forwarded to the University Committee in two to three years. As part of his research program with the company, he serves as an "external reviewer" in the annual evaluation of the Research and Development section of the corporation. In doing so, he signs a confidentiality agreement which covers the research activities discussed during the review.This year Dr. Johnson was inadvertently included in a discussion at the social gathering following the review where one of the corporate scientists revealed that they had been utilizing a widely recognized chemical synthesis to generate new compounds which could be used as antidotes to certain viral infections. Because of prior use and the obvious nature of the synthesis as presented in the literature, neither the process nor the compounds could be patented. Thus, as soon as word of this process leaks out, it would be available to any of their competitors.During the course of this conversation he learned that in secret trials one of the compounds reduced the mortality of Rift Valley Fever by 90%. About 5000 lives are lost annually to this and similar viruses in East African countries.The strategic plan adopted by the company was to withhold the distribution of those compounds. Management decided that they could not afford to release this compound to a developing country which would amount to a purely philanthropic gesture until after they had time to develop the compounds for influenza and the common cold. This would require about five years to obtain all of the permits needed to market such an antidote in developed countries. Unless the market in developed countries could be reached the antidotes would not be economically feasible to develop. However, if developed tens of thousands of additional lives lost to influenza would be saved.Ethical Dilemma:Should Dr. Johnson break confidentiality and reveal the process?
