Re: Basic Electrical Theory Questions- EASY

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

Re: Basic Electrical Theory Questions- EASY

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.

Re: Basic Electrical Theory Questions- EASY

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.

Re: Basic Electrical Theory Questions- EASY

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.
