What is Potential difference (voltage)?

Potential difference is like the push that makes electricity move from one place to another.

Imagine you have two buckets of water. One bucket is full, and the other is almost empty. If you connect them with a hose, the water will flow from the full bucket to the empty one because there’s more water in the first one, it has more energy to move.

Now think about electricity like that water. Potential difference, or voltage, is like how full one bucket is compared to the other. It's the push that makes the electric current flow from one point to another, just like water flows through a hose.

If you have a bigger push, more potential difference, then the electricity will move faster and do more work. Think of it like pushing a toy car: if you give it a big push, it goes farther and faster than if you just nudge it gently.

So whenever your toys light up or your phone charges, voltage is working hard behind the scenes, giving the little electrons their push!
