Non uniform charge distribution on conductor surface

In summary, a nonuniform charge distribution can exist on a conductor's surface due to an external influence such as a point particle located off the surface. This causes the charge on the surface to rearrange in order to maintain the same potential. Any external charge distribution can also result in a nonuniform charge distribution on the surface.

Hey everyone! I need some help.

Can a non uniform charge distribution exist on a conductor's surface due to some external influence? Please explain bearing in mind that a conductor's surface is equipotential.

Sure, for example if you have a point particle located somewhere off the conductor's surface. The presence of the point particle changes the potential everywhere in space, and so the charge on the conductor's surface has to rearrange itself to keep the surface at the same potential.

In fact, generally speaking, any sort of external charge distribution will cause a nonuniform charge distribution on the conductor's surface, for basically the same reason.

Thanks diazona, I got the concept. :smile:
 

1. What is non uniform charge distribution on conductor surface?

Non uniform charge distribution on conductor surface refers to the uneven distribution of electric charge across the surface of a conductor. This can occur when there are areas of the conductor that have a higher or lower concentration of electrons, leading to an imbalance of charges.

2. What causes non uniform charge distribution on conductor surface?

Non uniform charge distribution on conductor surface can be caused by a variety of factors, including the shape and size of the conductor, the material it is made of, and the presence of external electric fields. It can also be a result of the movement of charges within the conductor, such as during the charging process.

3. How does non uniform charge distribution affect the behavior of a conductor?

Non uniform charge distribution can have a significant impact on the behavior of a conductor. It can create areas of higher or lower electric potential, which can affect the flow of current and the distribution of charges within the conductor. This can also lead to the creation of electric fields, which can influence the movement of charges.

4. Can non uniform charge distribution be controlled?

Non uniform charge distribution on conductor surface can be controlled to some extent by adjusting the shape, size, and material of the conductor. It can also be controlled by using external electric fields to manipulate the distribution of charges. However, complete control over non uniform charge distribution may not be possible in all cases.

5. What are some practical applications of non uniform charge distribution on conductor surface?

Non uniform charge distribution on conductor surface has a number of practical applications. For example, it is used in electronic devices such as capacitors, where the uneven distribution of charges can store and release energy. It is also utilized in electrostatic precipitators, which use non uniform charge distribution to remove particles from gas streams. Additionally, it plays a role in the behavior of lightning and other atmospheric phenomena.
