That’s interesting – it’s the first time we’ve heard of this happening. What are you watching it on?
I tried adding a couple of blank lines after the video… try again and see if it has changed.
Hi Thomas,
I also saw your followup post that you read over the info about the Midterm.
Approach the Midterm as part of the learning experience. The open-answer format and a few of the questions we ask will challenge you to apply the basic electricity concepts that we’ve been teaching. It’s very common to need more than one attempt to pass this one, but it helps things to “click” for lots of students.
There are only 9 questions, but some of them may take some time to think about.

I love seeing a student paying attention to details! 😀
We want students to be comfortable with either letter. We say in the lesson:
Voltage is measured in units called Volts and is represented by the letter V or sometimes you’ll see the letter E used.
Keep up the good work!
Hi Darren,
The video played fine for me. More than likely if you closed/reopened your browser, and/or cleared your cache, it would play normally. But you aren’t missing much – he’s just talking about the valve near the bellows that can cause water to back up. You can basically read the text on the photo and understand the point.
Yep! And I see you found an older topic on this same question 🙂
Hi Darren,
Sure, you can always ask for a reset if you want to retake a quiz/exam for any reason. Just do so before moving forward. Do you know that there is a Quiz and Exam Reset Request form in the Campus Support menu?
I reset it for you.
R x I^2 = P (power, or watts). We aren’t looking for work in this question. (In other questions, where we are looking for heat generated by a load or a loose connection, you might use this formula.)
Remember, voltage is E (some people use V, but we usually use E in the course).
Since you are trying to find “E”, you want to look in the section of the pie chart for E. In other words, a you’re looking for a formula that starts with E = …
Hi William,
I’m glad you posted here. I emailed you using the address on your student account, but it bounced back to me. I tried your old gmail address that I had as well.
Please let me know what email address I can use to get in touch with you in the future!
Part 4 of #7 is incorrect.
And here’s a link to our Midterm Help Page.
Justin’s answer is close, but I don’t like to think of voltage as being “consumed.” Voltage measurements are always showing us a difference in charge between two points. Sometimes it’s between a point in our circuit and another known-good neutral point that is not part of the circuit (“wrt N”). Sometimes we are measuring voltage with our probes on each side of a load.
Which electrical property, that we can measure with our meter, is unique to loads?
Read the second paragraph of the first unit in the Motors Module:
https://my.mastersamuraitech.com/module-8/overview-of-electric-motors-used-in-appliances/
That’s it!
Correct!
That’s 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?
