This document discusses electricity and electrical charges. It explains that electricity is a form of energy used to power devices. Atoms are normally neutral, with equal numbers of protons and electrons, but some objects can gain or lose electrons, becoming positively or negatively charged. Charges can be transferred between objects, but the total charge is conserved according to the law of conservation of charge. Opposite charges attract and like charges repel through the invisible force of electricity.
Third Grading Module 6 Electricity
- 2. a familiar form of energy energy required to operate appliances, devices, gadgets and machines
- 5. atoms are neutral (no charge) the number of positive and negative particles are equal
- 6. some objects can lose electrons and some can gain electrons. why only electron is transferred???
- 7. the number of protons and electrons are not anymore equal there is more proton compared to electrons so the objects is said to be
- 8. the number of protons and electrons are not anymore equal there is more electrons compared to protons so the objects is said to be
- 9. the number of electrons lost is always equal to the number of electrons gained. LAW OF CONSERVATION OF CHARGE
- 10. Charges cannot be created nor destroyed, but can be transferred from one material to
- 11. an invisible force acting on charge materials or objects attract repel
- 12. Like charges repel and opposite charges attract.
- 13. happens when a neutral object is place near a charge object charges in the neutral object rearrange such that opposite charges are brought near each
- 15. the process of removing excess charges on an object providing a ground
- 16. any object that can be a source of unlimited electrons in order to neutralize the charged object GROUNDING
- 20. happens when two objects are in direct contact as object rapidly strip away, one loses electron and the other gains electron
- 28. a material that permits chargers to flow freely within it metals are usually good conductors of electricity
- 29. are materials that hinder the flow of charges examples are glass, porcelain, plastic and rubber
- 30. process wherein an object is charged without actual contact to any other charged object
- 39. process wherein a neutral object is charged by direct contact with a charged object
- 43. a path through which charges can flow
