Have you ever seen a ball on a hill? The ball can't move unless someone gives it a little push. The ball wants to roll down the hill because it has something called "potential energy." Potential energy is energy that is stored in something because of its position or shape.
Now, imagine that instead of a ball on a hill, we have a tiny electric charge. It also has potential energy because of its position. The charge wants to move towards a different position where it has less potential energy.
Scientists can use something called the "potential method" to figure out how this charge will move. They use math to calculate the amount of potential energy the charge has at different positions. Once they know that, they can figure out which direction the charge will move and how fast it will move.
This method is used a lot in things like designing electrical circuits and studying how different materials conduct electricity. So, just like a ball on a hill, scientists can use the potential method to understand how electric charges move from one place to another.
