# The voltage and current caused by a wave? Does distance matter?

## Homework Statement

If a wave is transmitted from an antenna with an amplitude of 5v and a receiver at 10 meters away and another is at 20 meters away picks the signal up. If they are the exact same receivers, will they register the same voltage? Will they register the same current?

## The Attempt at a Solution

Im going to say the voltage will be the same but the current will be lower in the one that is farther away.

How does the energy per unit area of the wave vary with distance from the source?
