The published specification and past papers can all be downloaded from here: http://wwwocrorguk/ qualifications/ type/ gce/ science/ physics_a/ documents/ students will sit the g484 examination in january and the g485 examination in may/ june of their a2 year module g486 is a coursework module and will be internally. Revision:capacitors and capacitance of an electrolytic capacitor results in them being damaged and possibly exploding non-electrolytic capacitors store slightly less charge but are not polarised and can be connected anywhere in a circuit aqa a a2 physics module 4 unfinished will add graphs and fill in gaps soon.
Time constant capacitors discharge exponentially that means that their charge falls away in a similar way to radioactive material decay in radioactivity you have a half-life, in capacitance you have a 'time constant' the rate of removal of charge is proportional to the amount of charge remaining // as time steps forward in. Capacitance – capacitor, dielectric, energy stored, capacitor discharge.

Delivery guides are designed to represent a body of knowledge about teaching a particular topic and contain: • curriculum content: a clear outline of the content covered by the delivery guide • thinking conceptually: expert guidance on the key concepts involved, common difficulties students may have, approaches to. capacitors are short term 'charge-stores', like an electric spring they are like batteries, although a battery produces e-s, capacitors just store them it consists of two metal plates separated by a layer of insulating material called a dielectric picture.
