How Does Charge, Current and Voltage | GCSE Physics | Doodle Science Work?

Think of charge, current, and voltage like a group of friends going on a rollercoaster ride, each one has a special job in making the fun happen!

Charge is like the kids waiting in line for the rollercoaster. Each kid represents a tiny bit of electricity, called a charge. The more kids there are, the more charge you have.

Voltage is like how excited the kids are before the ride starts. If they're super pumped, that means there's lots of voltage, which gives them energy to zoom off!

Current is what happens when the rollercoaster starts moving, it’s the number of kids passing a certain point every second. More kids going by faster means more current.

So imagine this: A full line of happy, excited kids (lots of charge and voltage) all rushing onto the rollercoaster at once, that’s a big current!

If you're on the rollercoaster, you can feel how much fun is happening, just like electricity flows in wires!

Examples

  1. A battery powers a toy car by moving charge through wires as current.
  2. Rubbing a balloon on your hair creates static charge, which can make it stick to the wall.
  3. Lights in a house turn on when voltage pushes current through the bulbs.
