How Does Electric Charge: Crash Course Physics #25 Work?

Electric charge is like a super tiny version of a magnet, but instead of sticking to your fridge, it can push or pull other charges around.

Imagine you're playing with balloons. When you rub one against your hair, it gets all charged up and sticks to the wall. That’s kind of what happens with electric charge: when things touch and move, they can gain or lose little bits of charge, like extra energy that makes them want to team up or stay apart.

Think of positive charges as kids who want to be friends with other positive kids, but don't like negative kids. And negative charges are the opposite: they hang out with other negatives and avoid positives.

If two same charges meet, say two balloons that both got rubbed against your hair, they push each other away, just like when you try to squeeze too many people into a tiny space at playtime.

But if a positive and negative charge meet, like a balloon and a wall, they pull together, kind of like how a magnet sticks to the fridge. That’s why charged things can stick or repel based on what kind of charge they have!
