I've already went through this post. Yet, I still can't understand the meaning of "density" of electric field lines whose number is, in reality, infinite.
One of the answers , for instance, states that the ratio of two densities is independent of the number of field lines, so even when their number is infinite, they would always end up canceling each other when computing the ratio of two densities ( for the field lines generated by a point charge), the mathematical proof of this statement makes sense. However, in reality, the number of field lines is infinite, and field lines don't cancel each other, so even if we get further from our point charge, the number of field lines per unit area would still be infinite, no matter how far or near we're from the source.
Am I missing something?
