There are two types of charge (positive and negative)

The structure of the atom

Like charges repel, unlike charges attract.

The principal of electrostatic induction ( why charged articles attract uncharged articles)

The (gold) leaf electroscope. Contact charging and charging by induction

Conductors and insulators.

Electric wind + lightning conductors.

LESSONS
