Doc Brown's GCSE OCR 21st Century Science-Physics Revision Notes

PLEASE NOTE NEW revision summaries for the NEW OCR 21st Century Science B GCSE Physics B and NEW OCR GCSE 21st Century Combined Science B Physics courses: Revision for Chapters P1-3 and  STARTING with Y10 in Sept. 2016 onwards, first exams in 2018

OCR GCSE 21st Century Additional Science Physics Module P5 Electric circuits

P5.1 Electric current – a flow of what?

• 1. Be able to explain that when two objects are rubbed together they become charged, because electrons are transferred from one object to the other

• 2. know that objects with similar charges repel, and objects with opposite charges attract

• 3. Be able to explain simple electrostatic effects in terms of attraction and repulsion of charges

• 4. know that electrons are negatively charged

• 5. know that electric current is a flow of charge

• 6. know that electric current is measured in amperes

• 7. understand that in an electric circuit the metal conductors (the components and wires) contain many charges that are free to move

• 8. understand that when a circuit is made, the battery causes these free charges to move, and that they are not used up but flow in a continuous loop

• 9. know that in metallic conductors an electric current is a movement of free electrons that are present throughout such materials

• 10. understand that in metal conductors there are lots of charges free to move but in an insulator there are few charges free to move.

• OCR GCSE Twenty First Century Additional Science PHYSICS

• P5.1 Electric current – a flow of what?
• When revising, these pages provide you with a summary of what you need to know and be able to do.

• BUT remember, your primary source of revision are your class notes, investigations and OCR 21st C GCSE science textbooks and classwork worksheets as well as examination practice with past papers.
