This is my first post but I have frequented the forum for a little while now. I tried to figure things out myself and often times I am lead here by google. So my question is this: How is the electric field of an object altered when the surface area of the object is altered? Example: Take a perfectly smooth sphere and charge it to 100 volts. Then take the same sphere and etch it to increase it's surface area 100 times. By that I mean similar to etching aluminium with hcl in capacitor production. When comparing the electric fields, are they different in anyway? My first thought was that by increasing the surface area; therefore capacitance, you would have more electric field lines on the altered sphere. Since those must terminate on a conductor or at infinity, it would have a stronger electric field. I was thinking with the idea that every charge carrier gets an electric field line. I don't think that is correct. Now I think the answer is that the electric fields are the same. However, the altered sphere would feel a stronger force if placed in an external electric field. Instead of individual charges getting field lines, I think it's more accurate to say that the electric field is a measure of total surface charge pressure. Can you guys shed some light on this or point me to something that will help me understand?
