How Does Electricity Travel Through Wires?

Imagine electricity like a line of people passing a ball. When you turn on the light, it's like someone at one end starts passing the ball quickly to the next person, and that movement is what lights up your bulb! The wire is just the path they use to pass the ball. Even though the ball only moves slowly, the whole line gets energized almost instantly.

Examples

  1. A flashlight turns on when electricity travels through its wires and makes the bulb light up.
  2. Your phone charges because tiny particles move through the charging cable.
  3. The lights in a building all turn on at once, even though the electrons are only moving slowly.
