AQA Physics: PHYA1 Tuesday 19th May 2015 (AM) and PHYA2 Thursday 04th June 2015 (PM)x

guys send help I got a U in the mock, I revised, just did a past paper and got 33%

OH MY GOSH, I FEEL THE SAME. ;(

guys do we need to know any proof for like resistors in parallel and series or any order things for unit 1 physics?

Nope, you can just use them without proof :smile:

can u teach me the whole syllabus pls

I will pay you with my tears

also you must be super duper smart if you dropped a subject you got full UMS in so props to you x

Can we please split the bill?

The smile on my face during a question where the battery has 'negligible internal resistance' :biggrin:

Couldn't find a paper with it in, I just wrote that myself.

Oh ok, thanks, its really useful.
Is the variable power source necessary? Or would a variable resistor simply do?
Also, for the reverse bias, would you have to say 'switch the wires around' for the current to flow the opposite direction?

Usually just so you can get a better understanding of it, it's always better to understand something rather than just learn what it is.

either a variable power supply or a variable resistor they are both acceptable and for the reverse bias u reverse the battery/cell OR the diode I don't think reversing the wires works

Probably not, I thin just a variable resistor would do. Reverse the terminals of the cell.

Yes, I believe I will provide my share of tears while raspberry saves them for another occasion. (Physics unit 2)
