ELECTRICIAN PLS COME OR MATHS GUYS IDK
Canada Goosebumps 
m.imgur.com/AGHqrz6?r I need help to determine Xs, i know to find it i just have to do sqrtZs² - Rs² Pls I'm stuck and it's an easy exercise.. But im dumb as fuck tho Sorry for the bad handwritting Rs=0 ohm Es=300v U=230v Cosinus phi=0.77 I=11A
2018-11-18 20:04
(i meant i know to find it its sqrt zs² - rs² but zs = rs + jxs) My bad
2018-11-18 20:05
I will look at it Electro + automation engineer here, gimmie a sec
2018-11-18 20:16
Thx for your time man

thats an overcomplicated way of writing it. In Sweden we always use somth called "visarform" idk what it means in English but good that you found the angles. Impedance is all about having the phase angles
2018-11-19 13:34
Second pic didnt upload imgur.com/a/5E1tXu3 Im right?
2018-11-19 14:55
It looks alright, 8.57 Ohm is also a realistic resistance for that component I wouldnt calculate it that way tho , there are faster ways
2018-11-19 14:57
I dont know these ways :( i always have to write all this

2018-11-18 20:07
i thought u were smart men
2018-11-18 20:17
i am men
2018-11-18 20:19
Meeen
2018-11-19 13:35
use the formulas given))
2018-11-18 20:08
yes
2018-11-18 20:09
Im not home right now but if no one helped u within a few hours i will.
2018-11-18 20:09
Thank you so much man
2018-11-18 20:10
Well if you do have the time to help me.. It would be really helpful man

ok
2018-11-18 21:30
did someome give you the answer yet? if not ill do it.
2018-11-18 23:58
Not yet, thx
2018-11-19 06:28
ok im a math guy, not an electrician, what is the problem looking for in words so i can find equations for it.

Jesus, thats looks hard AF. And i need to learn that stuff if i want the job i want :d
2018-11-18 20:10
its not men)) that was basic course in my 5 year long university in eletrical engineering
2018-11-18 20:17
Its basic yep, can u help?
2018-11-18 20:19
Its a serie so you have the same current through the whole circuit Idk the full exercise but you sould have the phase angle of the current then you can use the voltage over each component and get the impedance, then use the formula to get it on any form you like rectuanglar etc
2018-11-18 20:20
Exercise is in my last post, its french sorry but its the same also es and charge are reversed cuz its the 1.18figure and they say the 1.17figure which is the previous page of my book

M8, check #55 (just 2-3 comments down), i think Goosebumps helped you, not sure tho :)
2018-11-19 14:38
I already seen it, that some overcomplication Learn "visarform" in Swedish and you are good, just work with phase angles I studied electro in Lund University are u also gonna study this on uni

I am not 100% sure yet :) I mean, the job that i want is service technician, basically you need to learn some stuff about electricity, but not alot. You change filters in ventilation systems, check temperatures, check that nothing is broken etc. My friend did the class at Lernia, it takes about 12 months in "school" + 2 months out on the field before you get instantly hired since they need a bunch of people for those jobs. Something thats pretty nice is that you get paid on your 2 month "field training" as well! He got 10.500SEK, thats OK. Its a pretty easy job and you get a car and a pretty decent salary for the first year (Hes been on the job now for 2 years, he gets around 20.000 SEK each month, which isnt bad at all) :P He also gets a raise each year. Last year he started with 17.500 SEK each month because he was new, now, as i stated above, he gets 20.000 SEK + a card filled with a bunch of money that he can use to eat at places. Just imagine how much money he saves with that card.

2018-11-18 20:20
I could help if I had my exercise book lol Also I have no idea what Es is supposed to be

I think you wrote it wrong What is jXs? You drew a resistor symbol but you already got resistance as Rs = 0 Ohm. Why? If we assume you meant resistor the answer should be 20,9091, if you really meant jXs as a resistor, just like your symbol in your circuit meant
2018-11-18 20:37
imgur.com/a/Noq9Tv3 Sorry its in french but it's the same
2018-11-18 20:40
jxs is a coil
2018-11-18 21:13
U/Z = I friend :() and here U = 70 volt AC since u have 300V working against 230V
2018-11-18 20:54
he needs the phase angles of the current and voltage to calculate the imaginary part of the impedance

Hello, need some help with few physics exercises and can't write a separate post, hope somebody can help me too (sorry for being not on topic): 1.What is the strength of electric field inside metal cube (edge 4cm), if electric field strength outside the cube is 8V/cm. 2. What is the electric current inside conductor, if outside it flows 10V/cm. Don't really know whether these problems are correct (they come not from a very reliable source) but would really appreciate if somebody gave me a brief explanation on how to solve them if it is possible. Thanks in advance!
2018-11-18 21:17
Well is it electronic? Good luck man tbh i have no idea and never had such questio's wtf
2018-11-19 07:02
man you have a squares leaf and you have a lot of lines to not draw a deaf line wtf man how u want to know that value if u can't make a straight line
2018-11-18 21:27
So important
2018-11-18 21:29
of course it is important think when you are going to the next level which u have to draw bigger schemes
2018-11-18 21:29
Its 2018 bro we do them on computers also you're not helping at all
2018-11-18 21:30
still just computers now are the leafs you still should be smart enought to use your paper and not waste ur trees which make u be here typeing on hltv
2018-11-18 21:31
Okay? But idgaf about that just help me with that problem
2018-11-18 21:34
i dont know bro :/ i dont know those international signs your symbols are weird
2018-11-18 21:42
They're normal u just dont know them
2018-11-19 14:53

i remember doing these things easy af u just have to use same formulas over and over 0 secret JUst get the damn formulas and use them, anyways in ur grade they dont care if u understand it, in fact they dont want u to understand where it comes from

I learned this when I was 13 wtf
2018-11-19 14:50
imgur.com/a/5E1tXu3 Is it right?
2018-11-19 14:54
Idk been a long time since I last did it and I've forgotten the formulas for electrical currents because they aren't relevant to my current educational path
2018-11-19 15:13
Doubt u see that at 13 tho, maybe u=r i but thats it
