I have questions on signal power, energy, spectrum, and frequency in molecular level

[geshtapo]

signal power,energy,spectrum,frequency in molecular level

what is mean energy and power of signal in the conductor and relationship between power signal and electron in conductor?

All we know about frequency signal meaning but please explain for me what is mean in conductor and electron move?

In Fourier transform analysis we show frequency spectrum of signal that the signal made by infinite sine wave please explain

what is mean frequency harmonic in conductor and electron move?

You know square wave made by sum of sin wave how square wave made of by electron charge?

Thanks bro.

Re: signal power,energy,spectrum,frequency in molecular level

electrical engineering has many fundamentals . this forum is not intended to be a classroom for vague fundamentals.

there are many layers of analysis which do not need to examined for each principle.

e.g the conductor molecules and electrons do not move at the speed of the wave when a current flows. They act like dominoes with a wave velocity. so we do not consider electrons motion or energy in static , DC or AC analysis. THere is motion in the dielectric or very lossy conductors but in conductors electron flow is very slow and is not relevant for basic electrical study.

We only consider the charge, Q in a dielectric or insulator bound by conductors such that energy is E=1/CV^2 in the dielectric. We can have opposite polarity conductors in a medium but the energy is determined by the dielectric. THe conductors only add resistance which results in a voltage drop when current flows. V=I^2R

Conductors do not store energy unless they are inductive with current flow , and we do not call it energy of the electron.

Charges are static meaning no current flow. ( until there is discharge)

Do not confuse words of electron and charges with a Fourier transform of an AC waveform in your question.
AC means alternating current. Notice the difference in meaning or context.

For fun notice how amplitude of harmonics and PHase ( when enabled) affects the relationship between each variable in time and frequency domain. You may adjust any bar or select from menu.
