Static Electricity - Coggle Diagram

- - - - movement of charges
      - +ve & -ve charges
      - electrostatic attraction
        
        electrostatic discharge
        
        electrostatic charging
  - - - matter is made up of tiny particles called atoms, atoms are also made of particles
    - - like charges repel, unlike attract
    - - measured in Coulombs (C), charge carried by proton/electron is 1.6x10^-19
      - measured using a coulombmeter
    - - classified by their properties
    - - the study of static electric charges
      - electrical insulators do not conduct electricity, and are charged by friction
    - - process of charging the conductor without contact between charger and conductor.
        
        charged by induction not friction. (mobile electrons transferred to and away from conductors)
      - charging a single metal conductor by induction?
        
        -ve charged rod can be used for induction. Electrons will flow out to the ground during earthing. Makes the conductor +ve charged
      - discharging a charged conductor?
        
        done by earthing as electrons are free to move in conductors. (-ve and +ve charges become equal)
    - - illustrated with lines and arrowheads. Shows the behavior of a small +ve charge if it were free to move in the electric field along the lines
    - - an atmospheric discharge of electrostatic charges that usually happens during thunderstorms
        (reason why buildings have lightning conductors installed)
      - electrostatic discharge?
        
        electric charges can pile up on trucks cuz of friction btw roads and tyres (antistatic materials have a thin layer of metallised film; acts as a electrostatic shield for equipment placed inside
    - - uses static electricity to produce printed documents. (laser printers also use a similar process)
    - - when fossil fuels are burned in power stations to generate electricity, they produce waste gases and fly ash. (fly ash is concerning as it pollutes env)
    - - principles of electrostatic applied to spray paint vehicles. charged paint particles attracted to metal car body (earthed)
