If we have 1, then we have a watt. If we have 1000 watts, we have a kilo-watt. If we have 0.001 watts (1 divided by 1000, or one-thousandth of a watt), we have a milliwatt.
Correction: I accidentally wrote “microwatt” instead of “milliwatt” in my original reply. Sorry for any confusion!
Okay, thanks!
This question gives you the measurement of 4 megawatts and wants you to choose an equivalent value from the answers given. To find the correct answer requires that you play with the numbers some and push yourself to see how these conversions work.
The table is set up with “unit” being the center row. This is referring to “1” of whatever unit you’re talking about. In our case, for this question, we’re using “watts” as the unit.

And we can also take one amount, and convert the same quantity to a different term.
For example, if someone said we have 10 kilowatts, how many watts would that be? (Let me know your answer)
Hi Steve,
Happy to help, but you left off the Unit and question number from your topic. I’m not sure what you are referring to.
Hi Shannon,
One last question:
Are PTC thermistors used for temperature measurement or reaction?Hi Boyd,
Happy to help, but I’d like to get a little more specific a question from you. Please do re-watch the video, and then let me know what you need more info on.
Hi Shannon,
This information is presented in the video presentation at the end of this unit. It’s a long presentation, which is why we encourage students to pause and make notes.
The other trick is, assuming you’ve watched it all the way through at least once, when you need to review (to study for the quiz, for example), you can move forward in the video a little bit at a time and look for the slide that discusses what you are trying to review, and then re-listen to that bit.
A few questions or assignments to help make sure you get this material.
1. Do you understand what we mean when we say that sensors either are used for measurement or reaction? What would be an example of each of those?
2. For RTD’s: scrub forward in the video until you see the slide on RTDs, and rewatch for a few minutes to review where they are used.
3. To understand PTC thermistors, rewatch that section (about 45 minutes into the presentation), then let me know what PTC thermistors are used for and why.
Or – if you still have lingering questions after watching those bits, let me know!
Hi Shannon,
We do want students who need a reset on a quiz to post a topic in the Forums, but not just to request the reset. We want you to post a topic about what you missed after two attempts, so we can help you figure it out.
Please post a topic in the Appliance Parts forum about the material that you had trouble with on the quiz, and we’ll be glad to work with you to make sure you understand it. Then we can reset the quiz for you.
Yep, voltage drives current.
Thank you as you can tell not much electronic experience yet.
That’s okay! That’s the case with a lot of our students. Just take your time and be sure to ask questions here in the Forum if you need additional info or clarification as you go along. We are more than happy to help.
OL means “over limit”. When you see that, it means that the resistance reading is higher than the upper limit of your meter, so for all intents and purposes is “infinite” resistance (open) as far as the circuit is concerned.
Make sense?
Thanks for asking – elementary questions are great!
Yes – total resistance in a series circuit is simply the sum of the resistances of the loads.
Hi Raymond,
No problem – just reset you. By the way, please use the Contact form (“contact” in main menu) if you need to ask for something like this again. It’s a little better way to request a reset.
Thanks!
SusanSure, just let me know. And by the way, you can shoot us an email with requests like this from the Contact page (in the main menu).
Hi Michael,
It’s good practice – this is what you’ll often face when looking at a manual for a job!
In this case, there is a table of contents a few pages in. I just opened it myself and used the TOC to find the section where I thought the technical info that you mentioned would be, skipped ahead to those pages, and found what you are looking for.
See if you can do the same!
Hi Kyle,
I’ve sent 2 emails to you with a follow-up question I needed answered before I could finish grading your midterm. Do you get the emails to the address that’s on your student account at MST? (info@adv…)
You got it!
