Circuit Analysis

Electric charge is conserved. At any point in a conductor, the amount of charge (electrons) flowing in, will equal the charge flowing out of the that point. 

 In a closed loop of circuit, the sum of voltage drops must equal the full voltage.

 Series and Parallel Circuits:


When elements are connected in series, they are joined together in a line, one after the other, and the current has only one path to take.

 When connected in parallel, the elements are connected so the current can take more than one path. 

 RESISTORS
Resistors in series - more means more resistance
Rtotal = R1 + R2 + R3...

 Resistors in parallel - more means less resistance 



Voltage Dividers: an example of resistors in series. It is used to divide or reduce a voltage to a value needed for a part of a circuit. It has an input and output voltage. 
Transducers: devices that convert energy from one form to another. A type of transducer is known as a sensor, which creates a variation in voltage.

Common Literary Techniques in Tim Winton's 'The Turning'

Common techniques in Winton’s The Turning . Most of these examples are taken from ‘Aquifer’. Direct, concrete images: ‘In the afternoon the blue bush plain was hazy with smoke and the dust churned up with bulldozers.’ While these descriptions are simple and clear ways of describing the real world, Winton often highlights aspects that explore and reveal key aspects of the ideas or characters he is exploring. For example, the ‘hazy’ and ‘churned up’ elements in this description highlight 2 things: 1) the confused and often conflicting feelings of the narrator as he reflects back on a time of emotional and hormonal turmoil (growing up); 2) the murky and muddled interaction between past and present.  There is a tension or irony here in that the descriptions seem so straightforward and clear that the memories are certain, solid, can’t be argued with, which is true.  And yet how one grapples with these memories, how one mixes them/reconciles them with the present is less

Ionic Compounds

Image
Ionic Bonding: occurs between a metal and a non-metal results in a positive cation (metal) and a negative anion (non-metal) forms a salt, that is a lattice structured crystal that is more stable than the reactants Electron Transfer Diagrams Used to represent a reaction, showing the transfer of electrons Reactants on the left, products on the right Ionic Lattice: ionic compounds form crystals, a lattice composed of positive and negatively charged atoms in a regular 3D structure. They are held together by strong electrostatic attraction between oppositely charged ions. The atoms are packed in a regular repeating pattern. They form into the most stable arrangement with oppositely charged ions as close as possible and those with the same charge, as far away as possible. Properties Rigid as ions are tightly held Does not conduct electricity- no free charged particles in solid state, however, in molten or aqueous they are able to as ions have

Covalent Compounds

Image
Covalent bonds form between non-metal atoms. In order to reach stability, non-metal atoms want to gain electrons due to high electronegativities, so instead of stealing electrons, as in  ionic bonding , or giving them away as  metals  do, non-metals share. How sweet, they are so kind. Atoms share electrons so that they have a full valence shell. Remember Nobel Gases won't form covalent bonds/molecules as they already have full valence shells. Discrete Covalent Molecules: Exist as individual molecules: CO 2 , H 2 O, C 6 H 12 O 6 , HCl Many are gases / liquids at room temperature Generally low melting/boiling point poor conductors of electricity - no free charged particles, unless dissolved in water like dissolves in like (polar molecules will dissolve in polar molecules, same as non-polar will in non-polar) Covalent Network Lattices: Exist as a 2 or 3D layer lattice where each atom os covalently bonded to other atoms. Their properties vary greatly due to variation in s
