SUMMARY

In an AC circuit, the direction of current changes with each half cycle, and increasing the frequency results in a faster rate of change. At extremely high frequencies, the physical dimensions of conductors become critical, necessitating specialized designs to accommodate these frequencies. When frequencies exceed a certain threshold, traditional conduction methods become ineffective, leading to the use of alternative methods such as waveguides, fiber optics, and radiation. The discussion also touches on the fundamental principles of energy transfer from power generators to end-users, emphasizing the role of electrons in this process.

hi there,
In a.c. circuit, avery half circle, the current changes it direction. If u increase it, the changing rate is faster. So, this come to my mind, can u stop the current from flowing by using very very very high frequency? That is the changing of direction of flow of electron is too rapid that it won't move at all.
 
Physics news on Phys.org
As you approach high frequencies the length of the conductor is a factor and at very high frequencies the conductor must be designed to fit the frequency. When the frequency gets so high that you can't move power by shaking electrons, you use alternative conducting methods. Waveguides; glass fiber, radiation through space, etc.

Keep on chuggin !

Well, actually my question is will there be no current at all when the frequency is so high? From what u had said, does that imply that this can be happen?

Btw, how energy is transferred from the power generator far away to our house? i need some explanation on how the energy is carried out by the electrons.

Thx
