Study Notes

General Physics 2 - Electric Charge

  • Matter is composed of atoms and molecules
  • Properties of matter are mainly influenced by electrically charged particles: protons, electrons, and neutrons
  • Proton:
    • Mass: 9.1093897 x 10⁻³¹ kg
    • Charge: +1.60217733 x 10⁻¹⁹ C
    • Location: nucleus
  • Electron:
    • Mass: 1.6726231 x 10⁻²⁷ kg
    • Charge: -1.60217733 x 10⁻¹⁹ C
    • Location: outside the nucleus
  • Neutron:
    • Mass: 1.6749286 x 10⁻²⁷ kg
    • Charge: none
    • Location: nucleus

Electric Charges - Properties

  • Materials contain protons and electrons
  • Protons are positively charged
  • Electrons are negatively charged
  • Neutrons are neutral
  • A neutral body has an equal number of protons and electrons
  • Adding electrons makes a body negatively charged
  • Removing electrons makes a body positively charged

Law of Conservation of Charges

  • Charges cannot be created or destroyed, only transferred
  • The total charge in a closed system remains constant

Forces of Attraction and Repulsion

  • Opposite charges attract
  • Like charges repel

Charging Processes

  • Friction:
    • Rubbing two different materials together can transfer electrons
    • The object that gains electrons becomes negatively charged, and the one that loses electrons becomes positively charged. Examples include rubbing a balloon on hair.
  • Conduction:
    • Transferring electrons by direct contact between a charged object and a neutral object.
    • The neutral object gains the same charge as the charged object.
  • Induction:
    • Charging an object without physical contact with another charged object
    • Redistributes charges within the object, with the side closest to the charged object acquiring the opposite charge.

Charge Classification

  • Conductors: Materials that allow free electron flow. Examples include metals, like copper, aluminum and certain alloys.
  • Insulators: Materials that do not easily allow electron flow. Examples include nonmetals, like wood, plastic, rubber and certain polymers.
