Hi Everardo,

How about you go through the Basic Electricity module again.

Now that you know the questions on the Midterm exam, you would be able to look for the information that would help you to answer them.

Before I reset you, perhaps you want to write down or copy the Midterm questions.

Let me know if you want me to reset you.

[Susan Brown]

Sure – I reset you.

It’s mentioned at about 11:50 in the second video. We’ve taught what DC current is previously. I think given the three answer choices, there’s only one that is best.

A train on a track
A bullet shooting out of a gun
Water flowing through a pipe (note – I changed this answer – it will show up a little different next time you take it)

Hi Moishe,

A shunt circuit will have no load in it, but instead just a switch.

When we discuss a “parallel circuit” we are referring to a circuit that has at least one load in it.

Shunts are usually used in a circuit configuration where there is a load that sometimes needs to be shunted – in other words, have no current going through it. When the switch in the shunt is open, current will flow through the load that is parallel to it. When the switch closes, all current goes through that rather than the branch with the load.

Does that help?

Hi Everardo,

Glad to see you back at it!

I know it can be hard to put your question into words, and we deal with students on a regular basis who struggle with that problem.

Just take it one question at a time. For example, if you are still not sure how to get the correct answer for Question 3 on the Midterm, start a NEW topic in this Forum called something like “calculating circuit current”. Then you can just show me any ideas you have on how to do that calculation. Or, if you really don’t even know how to start, you can just tell me that.

The important thing in using these Forums is to look for our replies (make sure you check the little box that says “notify me of follow-up replies via email”). We’ll be going back and forth, trying to step you through the problem. The sooner you can reply, the sooner we can continue to help you.

Hi Ted,

Go back to the first unit in the course – Module 1, Unit 1, Orientation and read section 4, Get your reference book.

That tells you how to either order a hard copy of the book or how to access an electronic version.

[Susan Brown]

It’s the section further down the page on Circuit Protection Devices (since we are talking about things like circuit breaker panels).

[Susan Brown]

Technical documentation is often tricky and/or poorly worded. That’s the value of doing these exercises to get a little used to that.

We’re here to help!

Here are the two routes for L1 to get to that light. The bimetal that is circled is just called the light’s bimetal switch. In the documentation is says this bimetal is in the element’s temperature limiter.

[Susan Brown]

Hi Joe – only two answers are correct.

Through the protector bimetal is NOT one of them. The protector bimetals are the ones labeled “protector” in a different part of the diagram.

[Susan Brown]

Good, you’re seeing the right one now.

So when the switch closes L1 goes through the light and back to L2 through the red wire?

yes

Otherwise, follow that BK (J) jumper (the line on the schematic is not continuous) up to that where it joins in near H1.

[Susan Brown]

Hi Joe,

You may be looking at the wrong light. There is a single “surface indicator light” in one location on the schematic, and then there are 4 hot surface indicators lights, one for each burner. You want to find the LF light.

Let me know what you are looking at – how is it labeled?

[Susan Brown]

Tip for Question 9: there are 4 correct answers

Think about the sequence of events that led to the problem – spilling stew. Did you read the explanation that showed up in the quiz results?

Since we hear a spark, we know the spark module is at least trying to do its job. Also, since flame is established, we know the spark is being delivered to the correct location on the burner head and that the burner head is delivering the fuel-air mixture to the spark location. Therefore, there’s no reason to suspect the spark module, board, or electrode. The problem must be in the return current.

I reset you.

[Susan Brown]

Hi Joe,

Sometimes a little connectivity glitch can cause a problem with a quiz freezing up. As you’ve seen, it doesn’t happen often.

No worries – I reset you so you can take it again.
