      Yep! And I see you found an older topic on this same question 🙂

        Hi Darren,

        Sure, you can always ask for a reset if you want to retake a quiz/exam for any reason. Just do so before moving forward. Do you know that there is a Quiz and Exam Reset Request form in the Campus Support menu?

        I reset it for you.

          R x I^2 = P (power, or watts). We aren’t looking for work in this question. (In other questions, where we are looking for heat generated by a load or a loose connection, you might use this formula.)

          Remember, voltage is E (some people use V, but we usually use E in the course).

          Since you are trying to find “E”, you want to look in the section of the pie chart for E. In other words, a you’re looking for a formula that starts with E = …

            Hi William,

            I’m glad you posted here. I emailed you using the address on your student account, but it bounced back to me. I tried your old gmail address that I had as well.

            Please let me know what email address I can use to get in touch with you in the future!

            Part 4 of #7 is incorrect.

            And here’s a link to our Midterm Help Page.

              Justin’s answer is close, but I don’t like to think of voltage as being “consumed.” Voltage measurements are always showing us a difference in charge between two points. Sometimes it’s between a point in our circuit and another known-good neutral point that is not part of the circuit (“wrt N”). Sometimes we are measuring voltage with our probes on each side of a load.

              Which electrical property, that we can measure with our meter, is unique to loads?

                Read the second paragraph of the first unit in the Motors Module:

                        Okay, good.

                        So, now you can add circuit current, I, to the list of information that you know about this circuit.

                        You are trying to find voltage drop across each load.

                        You know the current going through each load and the resistance of each load.

                        What formula looks like the best one to use?

                          OF? or 0 degrees F that was a good one lol

                          Are you talking about #4? I’m not sure what you’re saying here… the question does use a 0 (zero)! Some people don’t pay attention to the word “exclude”.

                          #2:
                          From a systems point of view, with both compartments warm, you want to check the refrigeration system first. This doesn’t mean you won’t do your normal initial checks of sights and sounds when you first engage. Also, there could be other obvious symptoms that steer you in a different direction. But in general, this is the case.

                          What are your questions about this?

                            This question is testing you on the basics of circuits: current, voltage, voltage drop, open/closed circuits.

                            It is a 120vac circuit, so that means L1-N.

                            The load (the light bulb) is stipulated as being “good”.

                            What does the fact that you aren’t getting any voltage drop across the bulb tell you about current and whether the circuit is open or closed?

                              Read the section, “Dealing with multiple symptoms” at the end of Unit 2.

                                Thanks for replying – this is helping me to see where your mistake is.

                                Three more questions for you:

                                1. Questions 2, 3, and 4 on the Midterm are all about the same circuit, correct?

                                2. There is one other piece of information that you know about the circuit… you calculated it in Question 3. What is that?

                                3. Also, you wrote, “so we can find how much current(amps) is flowing through that part of the circuit”… in a series circuit, does the current change as it flows through the loads?

                                  Hi Nick,

                                  Thanks for posting a question!

                                  For any problem like this one, start with clearly writing down what you are asked to calculate, and what information you are given.

                                  So, for this question:

                                  1. What are you being asked to calculate?
                                  2. What information do you have about the circuit?

                                  Answer those two questions, then look at the Ohm’s Law pie chart and let me know which formula you think would be best to use.
