Think of a wire like a road, and electric charges like tiny, invisible “cars” moving along it. They aren’t literal balls you can see—they’re just a simple way to imagine charge moving. When these charges keep moving through the wire, that moving flow is called electric current. Now focus on one point in the wire, like a checkpoint. Current is about how much charge passes that point every second. If only a few charges pass each second, the current is small. If many more charges pass in the same time—or they pass more quickly—the current is bigger. We measure this with coulombs and seconds: if 1 coulomb of charge goes past the checkpoint in 1 second, that is 1 ampere. So, current is simply charge per second: more charge each second means more amperes.
