We want to hear your feedback! Share your scores and discuss the quiz, but keep it civil.

I liked it some of the questions were tricky.

· · · ·

poorly written quiz... some answers are absolutely WRONG!!!

· · · ·

Ok, I think it would weed out how much a person should do on his own, or when to get help.

· · · ·

I didn't like or agree with the wording on some of the questions. Some of the terminology was not standard to licensed electricians nor used in the National Electric Code.

· · · ·

I got 100% but some were questionable and not correct. I wish I knew this comment section was here I would have taken note of them but the answer was half right and the only answer close.

· · · ·

Obviously the questions were not written by an electrician. Several mistakes; some have been corrected in the list below. Some haven't... #19 Alternating current changes direction *occasionally*?? #52 Linemen and electricians don't do "electronics".

· · · ·

@tradeprosarenotgeniusus so whatd you score on this? just curious. I got 4 wrong.

· · · ·

Got 6 wrong, some strange answers. That use.

· · · ·

I got 9 wrong. I am not an electrician, I just have an interest in electronics.

· · · ·

Got one wrong but not an electrician. Just have an interest in electronics.

· · · ·

Got them all right. But I am a retired electrical engineer with 40 years of experience.

· · · ·

It's fun to read everyone's interpretation of something basic. I bet on the lineman/utility question about (guy wires) you probably said, "that's wrong they are called guide wires!" hahahahaha!

· · · ·

62 questions in 10 minutes with 8 wrong 2 I hit the button while page was loading....So it's a total of 10. I'm just an interior remodeling general contractor.

· · · ·

Took electronics in Tech school 35 years ago. Missed two "old age memory loss", or crs, "can't remember shit". Enjoyed the quiz though.

· · · ·

Not even electrician, did plumbing, iron work (rod buster), and fence installer. Damn good at all three as well, especially building fences

· · · ·

Too many construction workers who think they're a genius just for knowing there own trade. Yes I work construction, missed 5 on quiz, 3 due to screen juking me out

· · · ·

Hey Mr. 100%, guessing your an electrician or GC making this a case where you scoring anything less would be a concern. I'll bet your perfect score makes you feel superior to others out there

· · · ·

got 14 right must border on genius

· · · ·

100% although some questions are geared towards people with limited knowledge as some have pointed out here, but in the world of electricians that's how things work. I reality most people know in an AC circuit the current is alternating.

· · · ·

Got one right! ! If it can't be fixed with a hammer, than obviously it's an electrical problem!
