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

AI Thread Summary
When a wave is transmitted from an antenna with a 5V amplitude, receivers at different distances will not register the same current. The voltage at both receivers will remain the same, but the current will decrease for the receiver that is farther away due to the inverse square law affecting signal strength. Additionally, the energy per unit area of the wave diminishes with distance from the source, impacting the current received. Therefore, while voltage remains constant, current varies with distance. Understanding these principles is crucial for analyzing wave transmission and reception.

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?

Homework Equations





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?

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
