Carrier current

Okay kiddo, so you know how we can send messages to someone by talking to them or texting them, right? Well, sometimes we want to send messages through wires too, especially in big buildings like schools or hospitals.

Now, when we send these messages through wires, they can get weak and not very clear if they have to travel a really long way. That's where carrier current comes in. It's kind of like helping the message stay strong and clear as it travels through the wires.

Here's how it works - we take the message we want to send, and put it on a special signal called a carrier. This carrier is like a "carrier pigeon" for our message - it helps it travel through the wires without getting weak or unclear.

Then, we use a special device called a modulator to put the carrier and our message together, so they can both travel through the wires together. Once they reach the other end, we use another device called a demodulator to take the message off the carrier and make it clear for us to read or hear.

So that's the basic idea of carrier current - it's like a helper signal that keeps our messages strong and clear as they travel through wires. Pretty cool, huh?
