100 % baby, and that is the truth!

As was mentioned, when they asked "light", you had to realize they were referring to it as a means of creating electricity.

It’s a classic mnemonic (memory aid). The “L” is the symbol used for inductance, and the “C” is the symbol used for capacitance. “E” is for voltage (as in “electromotive force), and the “I” is for current. The “ELI” part is reminding us that the “I” comes after the “E” in an “L” device, which is to say that current lags the voltage in an inductor. The “ICE” part is similarly reminding us that current leads the voltage in a capacitor.

By the way, my score was 96%. I fell victim to a trick question, the exact wording of which I forgot. I am so ashamed. :rolleyes:

What was your AFSC?

I got a 96% also. My AFSC (Air Force Specialty Code) was a 331XX to start with and they changed it to 462XX. I was a Nuclear Weapons Specialist, worked on the Mark 28 warhead and GAM-77 Hound Dog missile (carried under the wings of a B-52). :)

Mine was 97. It was 100 questions and we were alloted 50 minutes, 30 seconds per question. It took me about 20 minutes, and I wanted more. It was fun! I knew a guy who got a 98.

On the basic electricity quiz here, I missed two, neither were electrical, for a score of 92.


Added: Oh, wait. The Air Force test was the AFQT (Air Force Qualifying Test). My AFSC, if I remember correctly, was 32834, Inertial Avionics and Radar Navigation Specialist. After all, this was 35 years ago.

Mine was 45 years ago (1963 to 1967 and active reserves 1967 to 1969).

Thanks, Charlie B for explaining that. That's helpful. :smile:

Crossman, I would have expected more out of you, no extra credit?
 
Questions 7-9, 16, 19 & 21 were either unanswerable or weird in some other way.
The worst test I ever took, and I got 88% anyway. I say the results are unreliable.
 
Disapointed with two wrong.

Like most tests, there is a fair part of bull in here. For example, the questions involving figure two; I've got no idea how to calculate that lot out, but, simplifying the data to what I could calculate in my head, only one of the answers seemed reasonable.
 
Don't know about the rest of you, but I think it would be interesting and worthwhile if we posted the questions we had trouble with and we could discuss them.

Most of the info in figure 2 was not needed. All you needed was the total voltage, total amperage, and PF to solve the two questions that I remember being asked.

Apparent power = V x A

True Power = watts = V x A x cos(angle)
 
@Crossman

All of which is true, but if you just forget about the power factor, there is still only one answer in the ballpark... So I got those questions right. Answering multi-choice exams is all about eliminating the crazy answers...
