That’s correct!

Hi Richard,
No apologies necessary! This is what we are here for.

Good question. There is a difference between the two diagrams. In Fig. 6-9 in the Kleinert book, there is a “series portion” and a “parallel portion”. The two loads in the series portion are in series with that whole parallel portion.

Here’s the diagram you’re talking about in the video:

The two loads that are in series, in the top circuit, are parallel to the other branches, not in series with them. Imagine electrons flowing back and forth from Line to N. In the Kleinert circuits, all of the electrons will have to travel through that series portion no matter which parallel circuit they also go through. In our set of circuits, that is not the case. Do you see the difference? If not, let me know, and we can continue to discuss. However – you’ll learn more about series and parallel circuits in the next unit as well, so that may be all you need.

Okay – let us know if you do need further help on anything!

I just emailed you

You don’t have to earn Certification, but I don’t understand why you won’t let us help you understand this information more. I’ll email you about this later today.

[Susan Brown]

No worries!

That’s correct! Good job.

Hi Daniel,

Doing conversions can be a little confusing until you get some practice with them. Sometimes it helps to practice with something you are more familiar with first.

For example, think about meter, kilometer, and millimeter. These are items you can picture, and relate to.

A meter is about the same as 3 feet (a yard).
A kilometer is about the same as a half of a mile.
A millimeter is a tiny little length.

Kilo is 1000 of something
Milli is 1/1000 of something.

So, a kilometer is 1000 meters. (You could phrase this as “converting” 1 kilometer to meters, which gives you 1000 meters. 5 kilometers would be 5000 meters.)

A meter is 1000 millimeters.

Or, you could say the opposite. 1 millimeter is 1/1000 of a meter.

For example, if someone wanted you to convert 1 meter into kilometers, would you take 1 meter and multiply by 1000, or divide by 1000?

Answer that, and we’ll go from there.

“Usually” is an important word! Here’s what we say in the unit

How long this valve is kept energized depends on the model, but it is usually kept on for 90 to 120 seconds.

So the best choice out of the possible answers we gave you is

Probably, but it depends on the model

Hi Josh, welcome!
Any of the units that you have completed can be gone back over, including looking at the quiz results. That is an important way to study for your exams!

Let me know if you have any other questions.

Hi Maksym,

Sorry about that – it shows up on my end. Sometimes it helps to close your browser and start fresh, and maybe clear your cache. Please let me know if it shows up for you after trying that.

I’ll include the image below.

Hi Joe,

Great job!

Most appliance repair companies are familiar with Master Samurai Tech and would be impressed with the fact that you earned Certification.

We have a Forum at Appliantology for techs who are looking for a job.

Also, we have a partnership with the Mr. Appliance Franchise organization to provide training to their techs. While I don’t have knowledge of each individual franchise location, as a whole Mr. Appliance is a great company. I know there is a location in the Indianapolis area.

I should be getting my next batch of Certificates from the printer shortly after New Years. I can always communicate via email to a potential employer if you don’t yet have the Certificate in hand.

Merry Christmas to you!

You can go ahead and put your answer here. I’ll just hide it after commenting on it 🙂

Hi Cynthia,
We’ll grade your Midterm this morning and email you about the results. You can move on a little in the course, since you do have another attempt at the Midterm if needed, but we advise people not to make too much progress until they’ve passed the Midterm.

The quiz on Mod. 4, unit 2 is a one-question humorous one, so don’t worry! 🙂

[Susan Brown]

The Final exam is largely based on the unit quiz questions that you encountered throughout the course. The biggest difference is when you get to the Open Answer exam and have to write definitions and do a few calculations on your own. The final exam has a higher first-attempt passing rate than the Midterm, FYI.

So the best way to study is to review each unit and quiz, to refresh your memory. If you’ve been keeping a notebook, that will help a lot.

Keep a calculator, pen, and paper handy.
