Electricity - Coggle Diagram

- - - - Battery
  - - - Copper wire
  - - - Electrical appliances, lamps, ovens
  - - - Switches, relays
  - - - Fuses, circuit breakers
- - - - Copper, silver, other metals
        
        Copper used as conducting wire
  - - - Plastic, rubber, glass, fibres, wood
        
        Plastic or rubber is used as protective layers on wires
  - - - Nichrome-made of nickel and chromium
        
        Nichrome is used as the heating element to convert electrical energy into heat energy
- - - - single loop or branch
        
        Only one path for flow of electricty
        
        plus- simple to build
        
        minus-resistance increase when more loads added
        
        minus 2-one load damaged, affects the functionality of other loads
  - - - more than 1 path for electricity to flow through
        
        plus-more loops added total resistance decreases
        
        plus 2- loads damaged, it does not affect the functionality of the other loops
        
        paralell circuit is used in the connectionof circuits in households
- - - - single loop, other components are the same or different
  - - - Total current,l, in the electric
        
        the total currebt-sum of current in all loops
- - - - Electricity can be transformed into other types of energy such as light, heat and chemical energy or mechanical energy through energy converters
        
        A circuit diagram is a drawing to represent a circuit using electrical symbols
- - - - Windmills or wind turbines, power stations
- - - - Dry cells, lithium cells, lead acid accumulators
- - - - Solar panels in calculators and photovoltaics
- - - - break in circuit
        
        No electricity flows
        
        caused by faulty working devices/break in protective devices
        
        eg. light bulb does not light up
- - - - circuit is complete
        
        Electricity flows non-stop
        
        eg. light bulb lights up
- - - - supplied by power source in the circuit such as electric cells
        
        Power source two terminals-positive and negative
        
        energy supplied by cells forces electrons to move out from negative terminal of source and flow in the circuit
        
        electrons flow back to positve terminal of source
        
        energy of source used up eventually not the electrons
        
        flow of electrons from negative terminal to positve teminal of a power source is called electron flow
        
        Conventional current model, used to indicate direction of electric current in circuit, flows from positive to negative terminal of the power source in a circuit
- - - - Voltmeter is connected in parallel with the resistors to measure the potential diference across the two points of it
