With fully answers... LOOKS LIKE WE GOT ANOTHER GENIUS, BOYS.
To all commercial residential electricians... In the last 5 years, when have you used parallel resistors and series resistors in a single circuit? The answer is zero.
End of the line resistors in fire alarm circuits to supervise open or short circuit conditions..
Didn't realize this was a residential practice test.. oh wait it ISNT!!
Really! Journeyman is the best reviewer for Electrician Exam
Question 1 is where in the code book ?
Thanks for the strategies you have shared here.

To all residential/commercial electricians, do u own a watt meter? Likely. A multimeter. How often do u use it to measure watts? Likely never.
No big deal but the Header above the answers states it as : Answers and Rationale. There is no rationale provided. Waiting for tech to become more interactive so if needed an explanation can be chosen. It's coming to a simple format like TH-cam soon.
Graduate with an Associates in EE technology in a semester and didn’t study for this got 5 wrong 3 were silly mistakes the other 2 literally had no idea 😅 just curious is the test really just this simple i feel like this is more or a beginner test if anything please let me know
where did you get this and what state is this for? I'm just curious. I'm trying to take a journeyman test in Washington
This may help.
NEC is your exam. It's the same for US, and open book.
NCCER will teach you everything you need to know as well as give your certifications which are kept in database for quick employer verification.
*State / Local ordinances vary. Check with your City / Inspector or a little reading. (www.necanet.org/professional-development/careers-in-electrical-contracting/licensure/state-code-licensing-requirements/state-electrical-regulations)
NEC- The National Electrical Code, or NFPA 70, is a regionally adoptable standard for the safe installation of electrical wiring and equipment in the United States. *(local ordinances can only make these rules more strict, never less)
NCCER- The leader in construction training, education, workforce development and accreditation.

How did you solve for question 19? Can someone explain?
so its 120V in the circuit and the current is 12A. but the lag is 60V. so you use the PIE Circle which you'll use (P= I x E) P=12x60 P=720watts - (A) is Amps & Current - (V) is Volts/EMF -Electromagnetic Force - (W) is Power/Watts
+Dallas Henderson Power in an AC circuit is given by the equation, P=Voltage by Current by Power Factor. In this case the Current lags the Voltage by 60 degrees...the Power Factor is always the Cosine value of this phase angle...and the Cosine of 60 degrees is 0.5...therefore, the power in this circuit is P=E x I x PF...that is, 120 x 12 x 0.5...equals 720 Watts.
Manuel Almanza and
Shamrock Shore thank you
Dallas Henderson You're welcome.
What’s the article number to question number 1?
Why do u as an electrician EVER need to know if voltage lags behind current or not?!
Q8 - COPPER is used in the fuse!
it asked inside of fuse. and tin has a low melting point. so tin it is.
Correct, Tin is not used in all fuses. Silver plated copper is common. Although NEC is known for asking questions that can be tricky. Some NEC questions expect you to fill in the blank. If you know different metals are used in fuses, it doesn't specify. We know a fuse has one purpose, break the circuit once overheated. Assuming the limited info from the question you should assume the lowest melting point.
So copper?
@@bambiemalone8457 No. Copper has relatively high melting temp at 1000C. Tin and lead alloy at 230C, which is more preferable in most application.
Thanks for helping out!
Why are all the questions leaning toward INDUSTRIAL electricians?! The common American electrician building our homes and commercial offices rarely need this. The engineer? Yes. Not us
nice work
I cant believe wattmeter can measure both ac/dc power?
Anyone know how the 19th Question is solved? plz let me know
can all of these questions be found in the NEC?
Nope, theory, like a Delmar's textbook.
Tell all answers with reason
In my reviewer, i have explanations :)
Nice
Thank you
Having trouble understanding 18 if I did my math correctly it should be 6 ohms 1 divided by 4 is .25ohm multiplied by 4 is 1 ohm pulse 5 is 6 ohms correct?
So the initial 5 ohms stays at 5 because its in series to the other resistors. Then you use the formula to find the resistance of the 4 resistors in the parallel circuit. So after applying the formula, the 4 resistors @ 1 ohm each come to 0.25 ohms. Then you add the two together making 5.25 Ohms.

Question 10
*__* thanks for this
what's up with that computer voice? 😒
Could you explain the answer 17, please
Power calculated with a phase shift is Voltage X Amperage X Cosine (angle)
We don't have the cosine (angle)
Efficiency = output/ input
Here o/p = 10 hp= 7460 watt
I/p = 9600 watt
Efficiency = 77.7%
i hope this wasn't asked by an electrician
@@beuriavlogs4379 how did you get 9600 as the I/p?
Any link for metal fabricator fitter ?
Super
someone explain me the answer 17 please
Is this for Utah?
This may help.

For china
ty
you have gud
Useless without explanation
Couldn't you afford to have someone VOICE the answers instead of this irritating AI/Computer bullshit? Come on.
Dear God, this is total bullshit! Out of 20 questions, pretty much 90 percent is motors. The apprenticeship, has you working commercial residential, NEVER seeing ANY of this.
just so you know, the testing is not suppose to test what you know about electrical rather how well you can find answers in the NEC codebook.. so yeah its going to ask you oddball questions
You forgot to add the rationale part. Absolute garbage.
Can’t trust most of these answers because y’all get the small shit wrong
.
question 11 the answer is wrong
check your ohms law. volts square divided by power(watts) = 1440 ohms. the answer is correct. or you can check amp=1.6 amps
Amperage is 166.666mA. Am i correct?
166.67mA
but 220v squared is 48400 divided by 40 watts is 1210ohms
TheJustReyes it’s 57,600.....
this sucked.
