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 ...

so, electric field doesn't contribute in energy transfer or what?? that I'm asking about

yes.

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??

why in electrical machines we says that magnetic field transfer energy in air gap but isn't there electric field also in air gap !

is it mean eath carry current for return ! in case of who say return is grounded how current return into supply!

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"

thanks very much

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...

I need to simulate machines in maxwell any tutorial for begainners like me?

why we haven't any connection other than Delta or star in 3phase

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
