All of AQA Electricity Explained - A Level Physics Revision

All of AQA Electricity explained for your A Level Physics revision. This video is revision of all the material you will be taught in your first year of A Levels. It revises some of the GCSE content you will be familiar with, including current, potential difference and resistance. Component characteristics are covered with the IV graphs for resistors (ohmic conductors), filament bulbs and diodes. Resistivity is introduced and the way that some semi-conductors decrease their resistance with temperature and some materials even have zero resistance at really, really low temperatures. Circuit rules are covered that include the conservation of charge and energy, the resistance of resistor combinations, potential dividers and internal resistance and emf. A complete summary of the topic. Don't forget of course that there are hundreds of in depth videos on my website that explain everything in this video in even greater detail.
