      You have a 120v circuit (L1-N) with two loads in series, R1 and R2. R1 = 20 ohms; R2 = 40 ohms. What is the heat generated by R2?

      The first step is to find the circuit current, I. Do you know what it is?

        Hi Leigh Anne,
        Good question!

        Yes, you could do that, but there are a couple of things to keep in mind.

        1.The only score we can see on our dashboard is the most recent one you’ve taken. So, if you accidentally scored lower on your second attempt, we would no longer see your first score. You can prevent this from interfering with earning Certification by archiving all of your emails with your quiz scores, so if you needed to, you could forward proof to me that you had a higher score on a first attempt.

        2. We encourage you to understand the correct answers to as many of the quiz questions as possible before moving on in the course, both for the sake of the knowledge itself, but also to increase your chances of passing the Module Exam. Sometimes you can glance at a quiz result and realize what the correct answer is, without needing to retake it. But sometimes retaking the quiz is going to be more effective.

        Hope that helps! Let me know if you have any other questions.

          See the “Volume Control” video in that unit, starting just after the 5 minute mark.

            Hi Denis,

            First of all, have you read the summary of voltage and voltage drop at this pinned topic?
            https://my.mastersamuraitech.com/appliance-repair-course-support/student-forums/topic/voltage-and-voltage-drop-summary/

            Voltage drop is specifically the difference in charge that we measure across one or more loads when current is running through the circuit.

            If current is not running through a load, then there will be no voltage difference across it.

            Does that help? Read through those, and let me know if you have follow-up questions.

              Hi Zach,
              Some of the units in Module 2 do not have quizzes. Instead, they just have the “mark as complete” buttons. If there is a quiz, it won’t let you move forward until you’ve taken it.

              So – you’re all set!

                Since we’re discussing actual answers, I’ll reply to you via email 🙂

                    Yes, each machine will have its own “key dance” to enter diagnostic mode, so the correct answer is, “Look it up on the tech sheet”

                    Let me know if you have any other questions.

                        4 Megawatts is 4,000,000 watts (You can type 4 megawatts in your search engine to see how many zeros it has, if you forget that Mega means 6 zeros. Mega = million)

                        The possible answers are:
                        A. 400,000 watts
                        B. 400 kilo-watts
                        C. 0.004 Giga-watts

                        So A is obviously not right.
                        A kilo is 1000, so 400 kilowatts is 400,000 watts (add 3 zeros to the end of the 400). So also not right.
                        C. Must be it. Let’s see: a Gigawatt is 9 zeros, or 1 billion. 0.004 x 1 billion = 4,000,000. yes!

                        Occasionally you have to know these things – but you can use your search engine to help you do the conversions. It’s good to know how to do!

                          Hi Yehoshua,

                          Read this topic and see if it helps. You haven’t gotten into parallel circuits yet, so don’t worry about that part.

                          If there is a particular quiz question you want me to step you through, let me know and I’m happy to.

                            We don’t currently have access to a scale, but our best guess is about 30 pounds.

                              Hi Jesse,
                              No, we don’t have something like that. The examples we use in the course are on just a small percentage of the thousands of models out there.

                              Are you wanting the manuals for when you are working on jobs? That is what Appliantology is for!

                              Be sure to activate your free 6-month Student Membership there. See the “Appliantology 101” short course at MST for how to do that.

                                Do you recognize these? You had the same scenario on the Midterm Exam in the Core course (the diagram just looks a little different).

                                Remember that when you have a single load in a circuit, that it will drop the full source voltage. Only loads in series will split the voltage drop. Loads in parallel will behave independently of the others.

                                The Safety is the clearest example of this – it is parallel to the other circuits.

                                The Main coil is wired in series with the Ignitor and Booster, which are in parallel to each other. However, the closed detector switch has a big impact on these circuits – it is what allows us to answer the questions without doing any calculations.

                                Is this ringing any bells?

                                  “open” is a better term than “missing”, but yes, L1 is the side with the fault.
