Electric charge — Core Learning Objectives
Note
- State that there are positive and negative charges
- State that positive charges repel other positive charges, negative charges repel other negative charges, but positive charges attract negative charges
- Describe simple experiments to show the production of electrostatic charges by friction and to show the detection of electrostatic charges
- Explain that charging of solids by friction involves only a transfer of negative charge (electrons)
- Describe an experiment to distinguish between electrical conductors and insulators
- Recall and use a simple electron model to explain the difference between electrical conductors and insulators and give typical examples
