Conductors Share a Voltage, Not a Charge

You'll learnhow charge really divides between connected conductors, and what a ground wire actually does.

A small charged sphere is wired to a big neutral one. Half each sounds fair. It is also impossible, and watching why teaches you what a wire actually does. Twelve short steps; press Next for each one.

a wire equalises voltage · the charge lands wherever that requires

Before you start

What you're looking at

Two metal spheres drawn at their true sizes. The number inside each is its charge; the number below is its voltage.

The question

Connect them with a wire: how does the charge divide, and what decides it?
