1. What is the electric field along a path through the air that starts at the + end of a battery, ends at the - end, and goes a large distance from the battery? In particular, what is the E field at those large distances?
2. Replace the path in 1. by the same path but along a wire between the + and - ends. What is the E field at large distances now?
3. And the point of this post is...... what causes the difference?
