The Electron and the Positive Charge
This is the little electron. He has a negative charge.
This is the positive charge. The positive charge is bigger and heavier than the little electron. He is the electron’s friend.
Positive charges are a bit lazy and do not like to run fast. Usually they just like to stay where they are.
