I have a question
I'm wondering in bode plot
we write the horizontal axis w rad/sec
what does this mean?
is it normal scale 0.1 0.2 0.3 ... etc with equal distances?? it's clear not because it's drwan on semilog paper
if it's the horizontal log w
why then we write 0.1 ,0.2 ,,1 ...
does u mean there is no elctric field at gap !
if yes! isn't electric field at conductor =0 then electric field exist outside conductors then it's electric field at gap !
how it's ?
why and how the surfaces grounded??
I didn't understand u
I'am asking about why the electric field...
what's negative frequency?
can we say s=-3 in example bode plot !
or we can say it's unstable at w=-3 rad/s
that's I mean is there negative frequency??
sorry friends
I got more worried
we difference between
1-single phase 2 wire
not as USA and has only 2 wires for current & return??
IN AC current alternate so, Isn't neutral must carrry current &therefore not safe
2-single phase 3 wire
as in USA there is 3 wires and there...
helllo ALLLLLL
my question
in Ac single phase without earth
only one phase live and one neutral
why we say that live line would kill but neutral won't kill
isn't neutral carry current for return "same live current"
conflict: why synchronous machine doesn't produce induced EMF in the DC field wires
Isn't it current path through winding which produce magnetic field (rotating) the must produce EMF in the dc winding of field (same theory of induction)
but why isn't true in synchronous
How we speak about the coil of primary in phase of a versus secondary coil
this is accepted (as there is on same core)
But question about
we say this transformer (ex) is vector group Dy11
that means phase difference between primary and secondary voltage is 330 angle
!
It's conflicted...
AC synchronous motor and generators
wikipedia as you know don't give all the data or problems or detailed information
I need reference books or lecture notes
what you recommend me to do
