This work builds upon the Y11 work from Additional Science. You should be able to derive the Kinetic Energy formulae, understand the concept of work done and how that can be expressed as an idea of Power. Also the efficiency of devices and some idea about how to apply that to real situations such as solar cells or power stations. The crux of this unit is to be able to construct calculations in your head without the use of usual formulae from a sheet. The way around this is to write down all the quantities that you know and then physically try and express the problem step by step. Don’t try and jump to the answer as you will get it wrong. Also check out your units carefully and check that match.

This quick setup shows how energy is lost when current flows in a wire such a power cable.
Using transformers we can step up the PD and reduce current flow I. This means that since...
Ploss= I*I*R. The reduction in lost energy is useful as the current is much reduced.
Take care though these cables have a PD of 160V which is very high and dangerous. NEVER touch the cable when it is on.Show More
