The notes resistor is misstated. The color code is clearly for a 47K resistor, as are the results.

Question 5.

Guyz, You want to kill me probably already

it is written 9.198 V, It is my mistake I am sure, would you please point it out for me? because I have broken my head already :

26*1320/(1000+1320+1000+270)
=9.5598885794

Question 28

Isn't it the opposite way: Vaf=-24 and Vdf=-12? Just I thought, that a resistor with higher resistance must drop more voltage.

question 29

Guyz, can not understand. tp1 and tp2 are common to the power supply points. How can it be that power supply points are still ok, but common to them points have different voltage? I am confused, help please.

 

Just be aware, there is nothing we can do with the worksheets at this time. They were tacked on almost as an afterthought by the original author of the AAC book, but no provisions for corrections were made. This issue is still an issue.

 

OK, but since I have to go through in any way (just for study's sake) I will report all the odds just in case or for future use.

question 35

if there were no perfectly sized resistors sized to choose from

Is one word "sized" superfluous?

 

perfectly sized resistors

Reads correctly, but

resistors sized to choose

is not correct.

permeability of free space do not understand what is T-m/At
relative permeability - it is written that relative permeability for air = 1, but the sign shows n0 instead of n1

Question 27

E-switch after 15 ms, isn't it -40.959*(1-e^-0.015/(10/1830))+40.959=2.6315+E-batt=11.6315?

Question 7

Instead of DC-AC inverter it is written DC-DC inverter.

 

The device in the illo is correctly labeled as a DC - AC inverter.

 

yeah, but the description is :
"An electromechanical alternator (AC generator) and a DC-DC inverter both output the same RMS voltage, and deliver the same amount of electrical power to two identical loads: "

Question 15

notes:
In a sense, resistance may be though of as a special (limiting) case of impedance, just as reactance is a special case of impedance.

Should it be written thought?

 

Yes, it should be "thought" instead of "though".

 

F**k! Yeah. got my mistake!!!

Q 9

Sorry, but I constantly have arctan(-1354.510153/1500) = -42.0822 degrees

Yeah. Because I am stupid. The same mistake as above. Sorry pipz.

Q 45

But the Xc is bigger in the fist case, so doesn't it mean, that C vector dominates?

Question 3

...circuit may then be converted into an equivalent simple-series or simple-parallel, which is mush easier to analyze.

Must it be much, not mush?

Answer to the question 36 states that the formula for notch freq = 1/(2piRC), but here http://www.allaboutcircuits.com/vol_2/chpt_8/5.html it is written that the formula is 1/(4piRC) which one is correct?
