Electricity flows through the internet via a complex network of cables and wires. When you access the internet, your device sends a request to a server through your internet service provider (ISP). This request is transmitted as electrical signals through the cables and wires of the ISP's network, and then through larger network infrastructure such as undersea cables and data centers. Ultimately, the request reaches the server, and the server sends back the requested data through the same network of cables and wires, allowing you to access the information you were looking for. **
