The Data Sheet AQA AS Level

DATA - FUNDAMENTAL CONSTANTS AND VALUES Quality – highlight the ones you have come across – most are from A2! Symbol Value - note most are 3 sig figs! Units – a useful place to look if you forget the case of the letter - N, kg, J, W, C, m etc.

Useful....

Probably not needed.. More an A2 requirement!

Fundamental particles No excuse for classifying them incorrectly!

Quarks They even tell you that antiquarks have opposite signs.... The fact that baryon number is in thirds tells you a baryon has three quarks in it!

Leptons Charges are indicated Masses etc are in data section...

Photons – Electromagnetic quanta of energy and/or waves The first two deal with e.m. Waves deBroglie links particles (momentum – mass) and waves (wavelength) – used to find the wavelength of a mass particle

Electricity The first four can be used to express definitions...

Current - I Electric current is how much charge moves in unit time (rate of flow of charge) Need to know Q is Quantity of charge

Potential difference - V Potential difference is the energy transferred per unit charge (coulomb).

Resistance - R The electical resistance of a component is the ratio of the potential difference across the component to the current passing through it.

Electromotive force -  The electromotive force is the energy per coulomb produced by a source of electricity.

EMF -   EMF = voltage across external circuit (IR) plus voltage across the internal resistance (called ‘lost volts’) Now V = IR – so we can replace that...  = V + Ir

Resistor combinations

Power – they already give you all combinations! (No excuse!!!)

Resistivity is not another word for resistance! Resistivity is resistance of a specimen of unit length and unit cross sectional area. Unit is  m not  – they are different!

AC I o is the peak current V o is the peak voltage I RMS is the root mean square current V RMS is the root mean square voltage

Oscilloscope This is in the waves section – and is needed to interpret the trace on an oscilloscope.
