3. What is it

3.1. build up of electric charge on the surface of objects

4. How it works

4.1. When two materials are in contact, electrons may move from one material to the other,

4.2. materials with weakly bound electrons tend to lose them, while materials with sparsely filled outer shells tend to gain them

4.3. Charge-induced charge separation

4.3.1. A charged object brought close to an electrically neutral object causes a separation of charge within the conductor
