But in physics infinity has a relative meaning. For example, relative to you, the area of your city is finite, but for a microorganism it is infinite because it will never be able to cross it. Similarly the dimensions of capacitor are so many times greater than the separation between them that those dimensions with respect to that separation can be treated to be infinite. And we are interested in electric field in that small separation only. | |

Sir can you plz plz plz plz explain it a bit....plz sir.. | |
