Electricity - Coggle Diagram

- - - - optional
      - gaps
      - control the flow of electricity in a circuit
  - - - therefore large currents can flow through a small circuit
      - flattens batteries quicker
- - - - copper metal
  - - - prevent the charge from being lost to the surroundings as it passes through the metal wires.
- - - - parts of atoms
      - Protons
        
        positively charged
      - Electrons
        
        negatively charged
      - Neutrons
        
        neutral
  - - - this causes one object to have more electrons than the other, therefore one will be negatively charged and one will be positively charged.
- - - - dry cell
        
        torch battery
      - wet cell
        
        car battery
      - They use chemical reactions to separate charges and produce current electricity through the wires
- - - - Ammeter
        
        tool used to measure amps
        
        must be connected into b the circuit
      - current
        
        measure of the number of electrons that pass a point each second
        
        measured in amperes
        
        amps (A)
        
        smaller unit = milliampere
        
        1000mA = 1 A
        
        1 (A) = 6 x 10^18 charges/second
        
        or 1 coulomb per second
        
        1 coulomb = 6 x 10^18
- - - - installed parallel to a circuit
- - - - the electron will pick up a certain amount of energy as it passes through each of the batteries
      - therefore if there are 2 1V batteries connected in series, then they will provide 2V of energy
    - - the electrons pass through one battery or the other and therefore they collect the same amount of energy. This way the batteries last longer
