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

        That’s it!

          Correct!

              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.

                          Hi Michael,

                          Here’s a quote from the “Math and Ohm’s Law” topic that is pinned at the top of this forum:

                          When you need to do an Ohm’s Law calculation, first ask yourself:

                          1. What am I being asked to calculate?
                          2. What information am I given?

                          In fact, it’s a good practice to write those items down on paper before proceeding.

                          In the question above,
                          – what are you being asked to calculate?
                          – what information is given?
                          – which formula is therefore best to use?

                          Please give me answers to those 3 questions.

                            “When it is discussing about the oven are they referring to the fact that all ovens must have a broil and bake element?”

                            Yes, that’s it. All ovens will at a minimum have a bake element and a broil element.

                            The surface elements/burners are on the “cooktop” portion of a range, not the “oven”.

                              Hi Darren,

                              Yes, that’s a new unit that we added recently. You are welcome to go through it at your leisure. there are no requirements for you to.

                                  This question reflects our encouragement to think in terms of “power” when it comes to loads doing work. They need voltage AND current, which is what power is (P = I x E). We get a lot of techs who focus only on voltage.

                                  So, that’s the answer we’re looking for – power.
