Telephone line
Okay kiddo, imagine you're playing with cups and strings with your friend. You hold one cup while your friend holds the other cup, and you talk to each other by speaking into the cup and listening through the other cup.
Now let's make the cup and string longer and longer until it reaches your friend's house. That's kind of what a telephone line is like! Instead of a cup and string, a telephone line is a wire that carries your voice from your phone to someone else's phone.
But how does it work? Well, when you talk into your phone, your voice is turned into an electrical signal that travels down the telephone line to the other person's phone. Their phone then turns the electrical signal back into your voice so they can hear it. This happens really quickly, so it sounds like you're talking to each other in real time!
Isn't it amazing how a simple cup and string game can help explain how something as complex as a telephone line works?
