Electricity

Electricity is an important way of transferring energy.  It has the advantage that it can be distributed nationwide from central power stations, where it is generated in bulk.  Electrical phenomena have been recognised by physicists for about two hundred years, and have been put to work over the last one hundred and fifty years.

In this unit, you will study the physics behind DC electric circuits and alternating currents.  You will also study the characteristics of some resistive transducers.
