Electric Charge
Bayani Gaba-gaba
Rub a balloon on your jumper and it sticks to the wall. Slide across a car seat on a dry day and a tiny spark jumps from your fingertip to the door handle. These everyday surprises are your first encounter with static electricity, a phenomenon that also powers photocopiers, cleans factory smoke, and poses real dangers when fuelling aircraft.
This topic explains how objects become charged, why charged objects attract or repel each other, and how we represent these forces using electric field lines. You will learn to distinguish conductors from insulators, trace the movement of electrons during charging by friction, and connect the physics to both its hazards and its practical applications.
Manufura
- Identify common materials that are electrical conductors or insulators, including metals and plastics
- Investigate how insulating materials can be charged by friction
- Explain how positive and negative electrostatic charges are produced on materials by the loss and gain of electrons
- Know that there are forces of attraction between unlike charges and forces of repulsion between like charges
- Explain electrostatic phenomena in terms of the movement of electrons
- Explain the potential dangers of electrostatic charges, e.g. when fuelling aircraft and tankers
- Explain some uses of electrostatic charges, e.g. in photocopiers and inkjet printers

Applications of Electrostatics
The study of electrostatics has proven useful in many areas. This module covers just a few of the many applications of electrostatics. Van de Graaff generators (or Van de Graaffs) are not only spectacular devices used to demonstrate high voltage due to static electricity—they are also used for serio
