What is voltage?

Voltage is like the push that makes electricity move through wires, just like a push makes a toy car zoom across the floor.

Imagine you have two buckets of water. One bucket is full, and the other is empty. If you connect them with a hose, the water will flow from the full bucket to the empty one. The more full the first bucket is, the stronger the push, that’s like voltage!

What voltage really does

Voltage is the difference in energy between two points. Think of it as the height of a slide: the higher you start, the faster you’ll go when you jump off. In electricity, voltage is like that starting height, it tells how much energy each electron has to move.

In real life, batteries give voltage. A AA battery might have 1.5 volts. If you stack two together, you get more push, 3 volts! That's why bigger batteries can make your toys go faster or brighter.

So next time you see a battery, remember: it’s like a full bucket waiting to send energy on its way!
