This part of the test is where common
sense, apprenticeship
and years on the job are helpful.

•20 EXAMS WITH OVER 700
QUESTIONS FROM 16 DIFFERENT CATEGORIES WITH DETAILED ANSWERS

When you
are actually sitting for the exam, your score is instantaneous but you never know what questions were
wrong or where your weaknesses are.

The elusive license, is still
unattainable at this point. How would the applicant ever find out what
the correct answer
is? They are not permitted to ever knowing the correctanswer. How are you
to be educated if you never
know the correct answer?

I can remember my third grade of school
when I miss
spelled a word and my paper had a big red mark on #7. With the correct
spelling of the word! You were taught to learn right from wrong by
showing you the correct spelling. It's called education.
A really positive learning experience. You knew where you made your
mistakes and where you needed to study to improve your education.

The only time you will ever know the "correct answer"
is when you read Tom
Henry Books where from all the
years of studying the intent of the NEC from the TCD, TCR giving the
substantiation for each of the new safety rules or deletions from the
NEC each three years.
At my age 82, I've been through 20 code
cycles and written over 90 electrical books which will give you the correct answer in full detail. The questions will be
worked in full detail
in the answer section of this book using the format or formula to solve
the calculation so you will fully understand how the correct answer was
solved.

Examples
from The Answer book:

In a 60 cycle system, what length of time does it take to go 90 degrees?

(a) 1/3 second (b) 1/90
second (c) 1/60
second (d) 1/240 second

If the resistance is held constant, what happens to the power if the
current is doubled?

(a) doubled (b)
halved
(c) multiplied by 4 (d)
divided by 4

*
Multiplied by 4.W= I2 R
Example: 10 amps x 10 amps x 10 ohms = 1,000 watts
20 amps x 20 amps x 10 ohms =
4,000 watts

Two 500 watt lamps connected in series across a 120 volt source. The
total power consumed is _______ watts.

(a) 1000 (b) 500 (c) 250 (d) 200

R = E2/W 120v x 120v/500w =28.8 ohms x 2 = 57.6 ohms. I = E/R 120v/57.6 Ohms = 2.0833 amps W = I2 R 2.0833a x 2.0833a x 57.6 ohms = 250 watts or W = E2/R 120v x 120v / 57.6 ohms =250 watts

How
confident are you with math calculations? Do you like to read and do
you retain what you read and study? Are you willing to schedule a time
to study and make this your #1 priority? Closed-book (No Book) exams stimulate deep learning more than open-book exams.
