HEY, I got them all correct
good little test, thanks Paul

[Paul W. Abernathy]

lol...yep just to bring everyone back to electrical theory basics...lol

[jferry]

Got 7, 12 and 13 wrong.

[Gerry Beaumont]

Hi Paul,

Good one, I can't believe I got question 1 wrong, I shouldn't do tests until the morning coffee has kicked in

when do we get the next installment of hard questions?

Regards

Gerry

[Paul W. Abernathy]

I would lOVE to do a weekly quiz installment.......of basic electrical and electrical training questions....you give the word and I will do a weekly, daily or so on program for it.

I just cant get enough electrical stuff...lol

You know Joe........those are the 3 that would KILL you in the field...tehehhe....Don't worry I got the same ones wrong on the Lawyer Bar Exam as well...thehehehe....the exact same numbers...

I've been killed a number of times at the roulette wheel by those same numbers.

lol...Now that frightens me joe....a lawyer that Gambles...lol.....hahhahah

I Oopsed on #13... I didn't read the whole answer.

Scores
14 of 14 100%
13 of 14 93%
12 of 14 86%
11 of 14 79%
10 of 14 71% If 75% or better was required to pass this or less would be failing. More studying would be in required.

[Jae Williams]

I breezed right through that thing...then I saw the answers!!
Oh, well...

Actually, I only got two wrong--one was #7 and I don't know why.

I remember in college on the final exam for one course in music I missed one
question--I answered 5/8 time as symetric. Well none of us are perfect.
always read and re-read the question and don't get in a hurry--the bus will wait for you.

Well, not all the time, anyway.

Good quiz, though. Let's do another real soon.

[Greg Bell]

Great post Paul.

Please keep them coming.

[lagudo]

Why not make this a course like the online Roofing Course that we have on our site now and upon completion we can get the hours needed for continuing education. Just a thought.
