Pre released background

The pre released material for your G492 gives you big hints as to what will turn up in section C for the paper. Here is some resources to help you understand each part.

Here is a nice summary of how to use a CRO: http://electronicsclub.info/cro.htm

Electric cars
Mostly this will be based on the data they have given you.
Comparison of different cars: http://www.which.co.uk/cars/choosing-a-car/eco-cars/electric-and-eco-cars-guide/
History of electric cars: http://en.wikipedia.org/wiki/History_of_the_electric_vehicle
Battery information: http://en.wikipedia.org/wiki/Electric_vehicle_battery
How the battery is made: http://youtu.be/Mun1Mct6JEs

The experiment written up properly (error analysis is a bit above what we need): http://www.physics.utah.edu/~ewalton/lab_report.pdf

Remember to get those questions from the student shared drive.

Pre released materials

In you G492 exam there will be a section C (this was missing from your mock). The questions are based on a pre released article: http://www.ocr.org.uk/Images/165500-unit-g492-advance-notice-june-2014.pdf. We will go through this in class and we are quite good at guessing what will come up. It is worth having a look through the article and start having a think about what you will need to work on.
