      Please watch the first video from 8:50 to 9:00.

      “Load” is a term you will see used a lot in the course.

      A lightbulb is an example of a load. Question 12 did not ask for an example of a load.

      When we talk about loads in appliances (the things that are performing their job – heating, moving, lighting, etc.), we will say they are “doing work” when they perform those tasks. “Power” is the measure of that work. A heating element does “work” when it heats up. Then we can ask “how much power is the element putting out while it is doing work?” and would find that answer in units of watts.

        Hello!
        The answer is “load.”

        A load is a component in a circuit that, when current flows through it, will do work (and – as you’ll learn, create a voltage drop across it).

            Hi Daniel,

            What the Samurai shows you in the videos is the result of decades of collecting tools, so you definitely don’t need to start with a big purchase.

            You can get started with a selection of basic hand tools and a good meter, then add on as needed.

            Your Appliantology membership is now active, so you can use the “Dojo” Tech Forum to get input from other working techs. Lots of guys there love talking about tools!

              The easiest way to think about this is to remember that the equivalent resistance of parallel loads will be smaller than the smallest resistance.

              The compressor windings, which are also in parallel, have resistances of 4.4 ohms and 6.25 ohms. The condenser motor is over 1000. So, the equivalent resistance of the motor and the compressor will not be much affected by the condenser fan resistance.

              Do you know what the equivalent resistance of the compressor windings is?

                  Hi William,

                  They are showing up for me, so I’d like you to try something and let me know if it helps.

                  Close your browser and clear the cache. Then, reopen it and try again.

                  Let me know if that helps. If not, please let me know what you are using to access the course – computer or device, and what browser.

                    Hi Chuck,
                    Hmm – I can see them on my end, so I’m not sure what’s going on there. Whenever you encounter something like that, it’s a good idea to refresh your computer – close the browser, clear you cache, then start fresh.

                    Please try that and let me know if the image shows up for you.

                    I’ll post a copy of it here just in case

                        Hi Everardo,

                        How about you go through the Basic Electricity module again.

                        Now that you know the questions on the Midterm exam, you would be able to look for the information that would help you to answer them.

                        Before I reset you, perhaps you want to write down or copy the Midterm questions.

                        Let me know if you want me to reset you.

                            It’s mentioned at about 11:50 in the second video. We’ve taught what DC current is previously. I think given the three answer choices, there’s only one that is best.

                              Hi Moishe,

                              A shunt circuit will have no load in it, but instead just a switch.

                              When we discuss a “parallel circuit” we are referring to a circuit that has at least one load in it.

                              Shunts are usually used in a circuit configuration where there is a load that sometimes needs to be shunted – in other words, have no current going through it. When the switch in the shunt is open, current will flow through the load that is parallel to it. When the switch closes, all current goes through that rather than the branch with the load.

                              Does that help?

                                  Hi Everardo,

                                  Glad to see you back at it!

                                  I know it can be hard to put your question into words, and we deal with students on a regular basis who struggle with that problem.

                                  Just take it one question at a time. For example, if you are still not sure how to get the correct answer for Question 3 on the Midterm, start a NEW topic in this Forum called something like “calculating circuit current”. Then you can just show me any ideas you have on how to do that calculation. Or, if you really don’t even know how to start, you can just tell me that.

                                  The important thing in using these Forums is to look for our replies (make sure you check the little box that says “notify me of follow-up replies via email”). We’ll be going back and forth, trying to step you through the problem. The sooner you can reply, the sooner we can continue to help you.
