Okay kiddo, imagine you have two toy cars that need help starting, but they don't have any batteries. Well, a jumper cable is like a magic cord that can help start those cars up by connecting them to another car that does have a battery.
Here's how it works: one end of the jumper cable goes on the toy car that needs help starting, and the other end goes on the car with the battery. It's like holding hands and sharing the power!
Once both ends are connected, the battery power from the working car flows into the toy car, giving it enough energy to start up. It's like getting a boost from a friend when you need it the most!
But, be careful, kiddo! Jumper cables can be dangerous if not used properly. So always ask an adult who knows how to use them safely to help you out.
