SUMMARY
The discussion centers on the behavior of voltage and current in relation to distance from a transmitting antenna. When a wave with an amplitude of 5V is transmitted, receivers located at 10 meters and 20 meters will register the same voltage of 5V. However, the current will be lower at the 20-meter receiver due to the inverse square law affecting signal strength over distance. Additionally, the energy per unit area of the wave decreases as the distance from the source increases, impacting the current received.
