    people don't leave me alone.... physics tends to become scary!

    What chapters are most of the questions in the past papers from?

    I wouldn't know.. I'm just reading a physics book.. so if you see on, let me know =]

    stopping potential, Vs, is the potential (voltage in a photocell) at which the photoelectrons don't have enough energy to go from the positive electrode (cathode) to the negative electrode (anode). This is like the maximum potential at which they have maximum kinetic energy. .. they can't get...

    yeh and induced current is taken in the conventional direction.. which means its the flow of positive particles, protons not electrons... but its okay if you believe that its electrons flowing from the positive terminal to the negative terminal, cause that totally makes sense right? =p

    thank god! I thought I was making physics up! ... do we need to know anthing about the stopping potential?

    oh I'm sorry... umm it's because the second finger gives the direction of conventional current, so from positive to negative .. that's actually the flow of protons (sorry my physics comes from everywhere else but the A level syllabus) Just ignore me.. it was something I noticed while doing...

    hey.. did you guys see any question with a circuit using a photocell in it?

    ack... this is gonna be a long 28 hour period..

    you people make it so much to remember.. the only difference, literally is that the right hand rule is when protons are travelling, and the left when electrons are flowing. Everything else is just force and field.

    so what's gonna help me more.. doing all the past papers, or reading the entire text book considering I only have 28 hours left before my exam?

    trust me... they will not give anything that will ask us to calculate the bandwidth, if they do .. just blame it on candidate number 0609, okay?

    I checked the syllabus and it doesn't say anything about learning how to calculate the badnwidht.. it only says "recall and use expressions for the voltage gain of inverting and of non inverting amplifiers" that's all there is about formulae from this topic.

    dude where the freak am I supposed to get a 1998 pastpaper from?! and just leave it.. they're not gonna give such a question in 2012

    this is why I hate A levels.. they teach you stuff which you later find out is bullshit, show me the question exactly and I'll give it a shot.

    I couldn't find anything in the textbook so no.

    technically you can't correctly calculate the bandwidth at all.. you can predit it though. Here: http://www.ecircuitcenter.com/circuits/op_bandwidth1/op_bandwidth1.htm

    yeh well .. i wanted to study in the last month but couldn't get myself to do it.. and dubai
