Current With Batteries

As I was playing Super Mario Land 2, which I do every Monday night, I realized that a current in the system was making it possible for me to play this great game. The two things needed to have a current is a voltage difference and a connection path. The electrons are flowing from the negative side of the battery to the positive side. As you can see I removed the battery cover so that you can easily view the batteries at work. President's Day is awsome.
