        Hi Jonathan,

        I’ll see if I can lead you to the correct answers for the first two.

        Select the true statement about voltage in parallel circuits:
        The correct answer choice has to do with voltage. When you have parallel circuits, do they each have the same voltage supply/drop or different?

        In parallel circuits, if one of the branches goes open the TOTAL circuit current ___.
        In the first video we point out that the total current in the circuits equals the sum of the current through each parallel branch. If one branch goes to zero, but the others stay the same, what happens to the total?

        Question #9 – The neutral connector in the circuit breaker box creates an area of
        The answer is “Low electrical pressure, or voltage, which completes the circuit and causes electrons to flow”
        Remember that to have current flow we need a difference in electrical pressure or charge, also known as voltage. The neutral provides an area of low pressure (ground potential) as a contrast to the Line potential, which is high.

        Question #12 – A ground fault is
        In the lesson we wrote:
        If the current flowing into the circuit differs by a very small amount (as little as 0.006 amperes) from the returning current, the GFCI interrupts power faster than a blink of an eye to prevent a lethal dose of electricity.
        So – of the answer choices we gave you – “an A current imbalance between line and neutral.” is what we were looking for.

          Yes, but as I mentioned above the extra material is not needed to pass the Final Exam. Even the blog post itself is bonus material and not required for the course.

            Hi Patrick,

            Are you talking about this part of Module 5, unit 3:

            3. Triacs are current controlled devices. This means that you need electrons bustin’ down the Gate to turn it on AND you need load current flowing through them in order to stay on.

            For more details on these fascinating devices, see this blog post over at Appliantology.

            The embedded link (“this blog post”) is https://appliantology.org/blogs/entry/953-triac-operation-for-appliance-techs/ , which is a blog post open to anyone to read.

            Perhaps you were then trying to click on some of the suggested workshop recordings from the blog post? Those are for Appliantology members only, and not necessary for passing the Core Course. Once you get your Alumnus Membership you will be able to view those as much as you want! 😀

              Hi Jon,

              You’ll have access to the lessons while your course access is active, which will be for 2 years, since you are enrolled in a Bundle. For most lessons we recommend making handwritten notes, as you’ll remember the material better. But for these particular units it’s okay if you want to copy paste the info for reference – for your own use only, please.

                You are correct – it is “From the disconnected DLB wire to the PR1 wire” because that is the circuit the broil element is in (that is our Load of Interest).

                Did you see the explanation that showed up for Question 3 in the quiz results?

                Although we are interested in continuity of the TCO, we’ll be measuring that through an element, which has a known resistance. There’s no way to test the switch without the load in the circuit (without doing a lot of unnecessary disassembly.) Therefore, we want the meter set to Ohms, not Continuity. The proper use of a continuity test is when you are testing a wire/switch only, not loads.

                      Hi Andrew,

                      The answer choices are: yes, no, or Efficiency doesn’t matter — that venting material is unsafe to use.

                      The last answer doesn’t apply to the semi-rigid material. So either the vent is or is not efficient, based on this criteria: “Semi-rigid tubing is efficient up to around 20 ft. with each 90 degree bend reducing this efficiency limit by 8 ft.”

                        Haha, we’ve had that question on the quiz for years but only just recently have gotten comments on it. What I’ve done is added the word “only” to the question to remove any ambiguity.

                        “Which types of dryers run on only 120 VAC?”

                          Yes, and we had been emailing with you about a month ago about setting up your account at Appliantology so we could upgrade it to the Alumnus membership that you had earned. I just checked and saw that you did set up an account recently, so I just upgraded it. You are now a premium tech member for a year. I’ll send you an email about it.

                            Hi Trevail (FYI – I moved your question to the Washer, Dryer, Dishwasher Forum)

                            Here’s a video at Appliantology on heat pump dryers:

                              Hi Nihar,

                              I think what he said is that it is a type of closed circuit. A circuit with zero resistance is definitely “closed” (it is not open somewhere) but also is a short circuit, because there is no load (resistance) in it.

                              Circuits in appliances will always have a load in it by design – an element, fan motor, light bulb, etc. When the circuit is closed, current will flow through it and power the load(s). If a short circuit occurs, that is a fault.

                              You’ll learn more about these things as you go along.

                              Does that help?

                                See the last video, starting around the 20 minute mark. It discusses the water valve being in series with the drain pump, and the implications of that. One thing it means is that if the drain pump winding has failed open, then the water valve would not be able to work. So – if water comes in, that means the drain pump (motor) winding is fine.

                                Winding: the drain pump is a motor, and motors have windings that the current goes through.

                                Does that help?

                                  Good catch! We reorganized some things since that video was recorded. Sorry for the confusion! I just added a link to the webinar recording – it is over at Appliantology.
