yes it is
The USPS has been terrible since December. We’ll send another one out to you next week and hope it makes it to you!
Best wishes on the new job!
Voltage is correct.
Not a load, though. A load is necessary in a circuit to prevent it from being a short circuit, but a load is not necessary for current. In fact, a load *resists* electron flow.
We’ve emphasized this in the Module – besides voltage, you need a ____ _____ for current to flow.
You are correct that there is no current flowing in the circuit.
But the problem is NOT that there isn’t “enough” voltage.
What two basic things do we need in order to get current flow?
those are correct
Hi Scott – thanks for letting us know – there is definitely something wrong with that link! I’ll get my IT guy to figure that out and fix it.
Sorry for the inconvenience!
the answers to Part 3 and Part 4 are not correct.
Did you rewatch the two videos at the end of Unit 4? They explain the scenario nicely (two circuits in parallel – what happens when one of them fails open).
Yes, that’s the answer. Do you understand it now?
First of all, did you rewatch the video at the end of Unit 5 where we talk about this?
Equivalent resistance is mathematically reducing two or more loads into just one.
It’s a little easier when we’re talking about loads in series, because all you have to do is add them (we call that “total resistance”). For example, if you have a 10 ohm load and a 20 ohm load in series, from the point of view of the power supply, it “feels” 30 ohms of resistance in the circuit. It doesn’t know that the resistance is divided up into two different loads.
Similarly, if you had a 10 ohm load and a 20 ohm load in parallel, the power supply would “feel” a resistance 6.67 ohms (that’s the equivalent resistance of those two loads). It’s just the way electricity works.
The question asks for the Equivalent Resistance of two loads that are in parallel. Resistance is in ohms. Current (amps) doesn’t come into it.
(I did mention this at some earlier point in this thread.)
Do you understand what we mean by “equivalent resistance”?
Hi Darren,
Things have been very chilly up here, but we’re doing great, thanks!
If you have a DMM with LoZ, then you don’t need a Wiggy.
We have considered selling merch, but haven’t implemented that yet. We love orange, too! (Partly from being Clemson alum.)
Our graphic designer had started working on some ideas a while back – we’ll get him going again and let you know.
Why are you trying to calculate amps there at the end?
Hi Tyler,
Rewatch the first video in Module 3 Unit 5 starting at about 11 minutes.

To successfully answer Question 9 you just need to know the basics of voltage, voltage drop, current, and L1-L2 power supply.
Look at Figure 1 and think about what measurements you would expect to get if the circuit were functioning properly. Remember that we tell you that the element has continuity.
IF the element was heating, what voltage drop would you expect to measure across the element?
Hi Mark,
You are all set – I see the 100% score.
The way our course software words that message is a little awkward. As soon as you start the second attempt, it changes it to say you’ve already used two attempts. It’s just jumping the gun a little bit with that message, for some reason. Sorry for the confusion!
