This causes more collisions with the oncoming electrons which increases the resistance. AQA A-Level Physics - Wikibooks, open books for an open world Visit author shop. This means that there is an increase in the resistance as shown on the graph as the potential difference is not proportional to the current. In thermistors the resistance decreases as the temperature increases. I'd love to create a personalised plan for 1-to-1 tutoring. and my physics one is coming up next week.

So if you’re revising Current and Voltage for AQA A-Level Physics, you can find all of the Current and Voltage questions that have been ever asked by AQA in one single document - useful, no? You need to be able to calculate the resistance of a circuit for resistors in series and parallel: Note that for parallel you need to take the inverse or the reciprocal of your answer in order to have your final total resistance. The Book of Electricity. Trending . They reduce the resistance to zero values which allows the current to be much higher than normal. Author: Created by physicsfairy. At this points the resistance is approximately zero and there is a very large current. Circuits – Current, potential difference, resistance and cells in series and parallel circuits, conservation of charge. Click on the topics below for notes and other resources: Topics.

Read the question carefully to ensure you know when you need to include internal resistance. Topic Questions; Past Papers; Revision Notes; CIE AS Physics 2022-2024. Created by teachers for Physics revision. Superconductivity is a special application where the use of strong magnetic fields help to reduce the energy loss when transmitting electric power. A diode has a forward bias where there is initially high resistance and a small current until approx 0.7V, after which the resistance rapidly decreases. So if you have two 1.5V cells in parallel - the potential difference of the circuit is….1.5V, Charge and energy are always conserved in a circuit.
