in quantum mechanics, these same pairs of variables are related by the Heisenberg uncertainty principle.
The energy of a particle at a certain event is the negative of the derivative of the action along a trajectory of that particle ending at that event with respect to the time of the event...
The concentration of flux in low-reluctance materials forms strong temporary poles and causes mechanical forces that tend to move the materials towards regions of higher flux so it is always an attractive force(pull).
what are these mechanical forces...
are they result of torque produced...
in Fourier transforms of normal baseband sigal , spectral components are replicated on both +ve and -ve sides of frequency axis.
i know that both -ve and +ve frequency components contribute to the total power of the signal
but i don't know the physical significance of the -ve frequencies...
eletric flux and charge have same units ie coloumb
is it a coincidence or some similarity exists btw these two?
electric flux density D= εE is used for calculating flux ψ not E .why?(read tht it is done for practical reasons) please explain the practical reasons ,if any.
let X be any hypothetical isolated neutral atom and X- be the anion formed when X gain 1 electron
this extra electron is in the valence energy orbit(band) and X- being charged produces electric field
check me if i m wrng above
now X(neutral) also consists of electrons in the...
is it true that analog signals are the logarithmic version of the natural signals... and hence the name a-na -log.?
what is the meaning of infinite information contained in analog or continuous valued signal?
please elaborate
