Chapter 13 (Electricity) - Coggle Diagram

- - - - Fixed resistors
      - Variable resistors
        (rheostats)
      - To control the amount of current in circuits, resistors are used (Prevent Overheating)
- - - - Electrolysis
        
        Electroplating
        
        Coating a metal object with another metal using electricity
        
        Item: Negative terminal
        Metal used for coating: Positive terminal
        
        Extraction of metals (Aluminium)
    - - Copper wire has low resistance which produces less heat
      - nichrome wire has high resistance which produces a lot heat
    - - Electromagnet
        (Control strength and switch on/off)
    - - A resistance wire(tungsten)
        
        Electrical energy→Thermal energy→Light energy
- - - - path of very low resistance between 2 points
        
        large current flows through
        
        very hot, very
