Do you guys have any predictions for the physics 6 markers? It probably won't be Herschel and Ritter because that came up last year, didn't it?


Generating Electricity the one with slip rings and carbon brushes.

I actually predicted correctly on Nitrogen Cycle for Biology and Liquid Paraffin for Chemistry :u:

what do you mean 'Generating Electricity the one with slip rings and carbon brushes'? Could you explain please:smile:

In industry, electricity is generated by spinning a coil of wire in a magnetic field.The carbon brushes act as contacts with the slip rings, so that the current can always flow from the coil to an external circuit. Its basically just moving a magnet with coils on through a magnetic field to make electricity - you'll probably have to revise how to change the current too eg. spinning it faster, more coils = bigger current

wow im going to start revising that now!
good luck everyone hope you do well in tomorrows exam:smile::smile::wink:

Oh so electromagnetic induction ?

I thought that was p2? Why would p2 come into p1?

I think its about electromagnetic induction which is P1

Have you finished the syllabus? What are your marks/grades on the past papers?


"edexcel only?"

bit inclusive.

But the carbon stuff thats been predicted we've never learn that, have you?

What carbon stuff? The carbon rods?

Oh no I didn't know about that haha

i didn't think this was on the spec?

If ur talking about the carbon brush and slip rings, I didn't know about that as well and won't bother learning it haha.

electromagnetic induction came up on last years paper
evidence: explain how this current is induced in the coil in the model.
