Ammeter is used to measure the current through the resistor, must be in series. They are written for the AQA exam board but should still be useful for all other exam boards, including Edexcel, and OCR A and B.

Revision for CIE AS and A-level Physics (9702) papers, including summary notes, videos, factsheets and past exam questions by topic. Physics Notes G.C.E. Physics was my worst subject throughout the year but when it came to revision time I found your channel and ended up getting 93% overall in the AS level! Paper format: There are two questions in each paper. The A-Level Revision section of Revision World where we provide free A level revision resources for a range of subjects including: Biology, Business Studies, Chemistry, Economics, English, Geography, History, Media Studies, Maths, Physical Education (PE), Physics, Psychology, Religious Studies (RS), Law and Sociology. A resistor is an electrical component that limits or regulates the flow of electrical current in an electronic circuit. A Level Physics Online I just wanted to say a huge thank you for your videos. The emphasis throughout […] When the spring is wound, it stores the ability to do work. Subcategories. When a voltage is applied across the metal. No current must pass through the voltmeter otherwise the ammeter will not record the exact current through the resistor. Soviet Union Edexcel Spec 2015. You also need to know that the area under the line gives you the displacement of the object up to that point. IMPORTANT!!! these conduction electrons are attracted to the positive terminal of the metal. These will either be practicals where you will follow a method and collect data before analysing it, or there will be methods that you will have planned yourself. The syllabus includes the main theoretical concepts which are fundamental to the subject, a section on some current applications of physics, and a strong emphasis on advanced practical skills. A thermistor at constant temperature gives a straight line. The variable resistor is used to adjust current and pd. The current is due to the passage of charged particles: Charge carriers. Also, check out our other helpful revision resources for O Level Physics (5054). Typical results for a diode are shown below, a silicon diode conducts easily in the forward direction above a pd of 0.6V and barely any below 0.6V. One kilowatt-hour is the energy expended when work is done at the rate of 1 kilowatt for a time of 1 hour. In order for automobiles to work for us, they need to be powerful and energy efficient. Find A-Level Physics Revision Resources + Edexcel, AQA & OCR specific Physics Revision Resources for A-Level Students. When current passes through it, there is no PD across it because resistance= 0. Notes for CIE. FAQs. This category has only the following subcategory. Chemistry (0620) Economics (0455) Physics (0625) AS. Consider an automobile engine. All the MCQs have been compiled according to the year in which they were set The Best Physics AS and A Level Notes, Revision Guides, Tips and Websites compiled from all around the world at one place for your ease so you can prepare for your tests and examinations with the satisfaction that you have the best resources available to you. A Level Notes. The current is due to the passage of charged particles: In metals, the charge carriers are conducting electrons, which move about inside the metal and collide with each other and the other positive ions in the metal. Work is done when a force moves to the point at which it acts (the point of application) in the direction of the force. (Equivalent to Advanced Placement) If this is too advanced … Work, energy, power and efficiency are important terms in analysing the performance of machines. AS > Physics (9702) Complete AS Notes: Notes. Formulas: Sheet. While solving questions the formula sheet makes it easier for students to study, they have all the formulas at one place and do not need to look for the formulas from the books again and again. Resources include A-Level Physics Revision Notes, A-Level Physics Help Forums (General Revision + Edexcel, AQA, OCR & WJEC), Exam Specs, Exam Papers, Physics Revision Guides (A Level) & More. This allows them to be used in light sensing circuits. Physics Revision For each of the exam boards below, there are revision notes, factsheets, questions from past exam papers separated by topic and videos. Current is the rate of the flow of charge in the wire or component.
