Charge distribution inside an electron

Click For Summary
The discussion centers on the charge distribution within an electron, questioning whether it is uniform or concentrated in specific areas. Current theories do not provide a clear model for electron charge distribution, as electrons are considered point particles with no defined size. If the charge were non-uniform, it would result in an electric dipole moment; however, experimental measurements indicate that any dipole moment is negligible, with values published as (0.07±0.07)×10−26 e·cm. This range suggests that the dipole moment could effectively be zero, implying an even charge distribution. Overall, the lack of measurable dipole moment supports the notion of uniform charge distribution in electrons.

Is the charge distribution of an electron uniform, or is there more charge concentrated near the center or perimeter?
 
Physics news on Phys.org
There are no indications of any size of an electron, and even for new models I am not aware of any good theory that would allow to discuss something like a charge distribution of an electron.
 
If the charge is distributed in a non-uniform way, it should have an electric dipole moment with perhaps more charge on one side compared to the other. Experimentally, the electric dipole moment is too small to measure in all experiments to date. The Particle Data Group publishes its value as (0.07±0.07)×10−26 e·cm. Notice this range includes 0. No dipole moment still does not answer your question, it just assures you it is evenly distributed.

Thread 'What determines if wave components are independent vs coherent?'

I'm working through something and want to make sure I understand the physics. In a system with three wave components at 120° phase separation, the total energy calculation depends on how we treat them: If coherent (add amplitudes first, then square): E = (A₁ + A₂ + A₃)² = 0 If independent (square each, then add): E = A₁² + A₂² + A₃² = 3/2 = constant In three-phase electrical systems, we treat the phases as independent — total power is sum of individual powers. In light interference...
