Electric Charges
- Two types of electric charges: Positive charge (+) and negative charge (-).
- Each positive charge when brought in contact with negative charge, they nullify effects of each other.
- Like charges repel each other while unlike charges attract each other
- An object having some charges is electrified or charged object.
- An object with no charge is electrically neutral.
| Rubbing materials | Positive Charge (+) | Negative Charge (-) |
|---|---|---|
| Glass rod rubbed with wool or silk cloth | Glass rod | wool/silk |
| Plastic rod rubbed with cat’s fur | cat’s fur | Plastic rod |
