What are voltage differences?

Voltage differences are like the push that makes water flow through a hose, but for electricity.

Imagine you have two buckets: one is full of water, and the other is empty. If you connect them with a hose, water will start to move from the full bucket to the empty one because there’s a difference in how full they are. That difference is like a voltage difference, it’s what makes electricity move.

Think of your body as the water. When you eat something sweet, like candy, your blood sugar goes up, that's like having a high voltage. Your cells need energy to work, so they take in the sugar. The difference between high and low is what keeps things moving, just like how electricity moves when there’s a voltage difference.

Imagine you're on a slide at the park. If you start from the top, you go fast, that's like having a big voltage difference. But if you start near the bottom, you don’t go as fast, that's like a small voltage difference. The bigger the difference, the more energy flows!
