Hi Starobin,
L2 is supposed to be hot (120v), but it isn’t in that scenario. There’s an open somewhere on the L2 side preventing current from flowing in the circuit.
Hi Ben,
1. Yes to both, basically. You’ll create the folders in Goodreader, which will also store them that way. It’s straightforward – just start using the app and you’ll see.
2. We don’t have files available as a massive download, nor do we recommend people try to do that. You’ll just end up with thousands of files you will never use. As you know, we recommend you have an SOP (Standard operating procedure) with your jobs that involves downloading the docs you need ahead of time. Occasionally, the file you need will not be in our downloads section and you’ll need to request it. You’ll gradually build up a library of docs for models that are common in your area, and will be adding to it regularly.
The number of times you’ll go on a job without advance notice is small, and then there’s no guarantee that the doc you would need would be in the big stash. So, it’s not worth changing your SOP for this circumstance. And, hey – sometimes the tech sheet is still on the appliance!
There are some questions where you have to do calculations. If you show your work, then that increases the chance that you can get partial credit even if your final answer is incorrect. For example, if you start out with the right approach, but make a math error, you could still get a lot of points. If you simply put down an answer and it is wrong, we can’t give you any points.
Is that what you mean?
By the way, most of the questions are answered by descriptions or definitions, all based on the material that we’ve taught and tested you on in the quizzes. There are only a few calculations that you have to do.
The main thing to keep in mind is that a short is a path from line to neutral or ground with NO load in it. It will result in a fault of some type, usually blown fuse.
A shunt is a bypass around one or more particular loads in a circuit, but not all of them. There will still be at least one load between L1 and N.
Yes. As a result, there’s no current, and thus no work being done.
Right – and what does that tell us about the functionality (or lack thereof) of the circuit?
If you aren’t quite sure, think about what creates voltage drop.
Question #6 – You’re troubleshooting an electric dryer for a no-heat complaint. The schematic is shown below. You start the dryer in a heat cycle and measure 0 V AC across the heater with both wires still connected to the heating element. What does this tell you?
We are measuring across the heater. L1 wrt L2. In other words, looking for voltage drop across the heater.
What does a zero measurement here mean?
Hi Ag,
Closed contacts are the same as a closed switch. Is there voltage drop across a closed switch? Review the Core course, Basic electricity module, unit 8.
Hi Tyler,
I did go ahead and set you back to Module 4, unit 3, where you had scored under 80% on your second attempt at the quiz.
Remember, you need to score 80% or higher on EACH unit quiz, 90% or higher on EACH exam, in order to earn Certification.
Review the Orientation for details and tips on how to do well on the tests.
For future reference, if you need a reset, please use the Quiz and Exam Reset Request form (in the Campus Support menu).
Okay – we fixed the code. Thanks again!
Hi Vukomir,
Thanks for the heads up! Something changes with the coding on those videos. I’ll get my IT guy to fix them right away. Please check back soon.Hi Brad,
You did calculations like that on the Midterm exam. Specifically, questions 4 and 6.
See also Basic Electricity, Unit 3 (the last video) and Unit 8.
From the unit:
Gate stations serve three purposes. First, they reduce the pressure in the line from transmission levels (200 to 1,500 psi) to distribution levels, which range from ¼ psi to 200 psi. Then an odorant, the distinctive rotten eggs smell associated with natural gas, is added, so that consumers can smell even small quantities of gas. Finally, the gate station measures the flow rate of the gas to determine the amount being received by the utility.
Note – the other question you missed, #6 – you have to do a conversion to figure out which answer choice is correct.
Hi Shamshon – please check your email – I’ll reply to you there.
Hi Tyler,
If you are required to earn Certification for the course, then you’ve got several scores that are below the required mark, starting back in Module 2, unit 8.
As for answers that you think are correct but we are saying they are not, you will have to give me specific examples. I glanced at some of the ones you missed and they are in fact incorrect.
Also – be careful getting help from other people. We’ve seen lots of people teach this material incorrectly. Why not get help from us? We’ve trained thousands of techs, so we should be able to help you, too.
Before I reset you, let me know which questions you think are not being graded correctly, and if you are required to earn Certification.
