I didn't sit it, or not this year at least

I think 12 is D, i asked my physics teacher and they said 12 was D.

I got D too, I think it's because the voltage is the same at both points in the parallel resistors so the voltage would split between V1 and V2 and V3 but V3 and V2 are equal so it would be the same as setting up one voltmeter. V1 + V2 = Vs. sorry I hope I don'y confuse you more.

I just thought that it split up randomly when it reached the first parallel circuit (splitting into two sections before getting to the parallel circuits for each resistor)

Live and learn, I’ve got over 95% in all my physics tests this year I’m hoping for an A but cheeks crossed x
"live and learn"; couldn't have said it better myself :thumbsup:.

It spilts randomly between two resistors in series. so the parallel branch can be considered one resistor in series with the other one. Whereas in parallel, voltage is the same at all points so V2=V3 but its not been spilt its the same. since its the same the voltage across V2 could be considered the voltage if there was only one resistor in series with V1. so V1 and V2 could be in series and add up to Vs

You're probably right, electricity is my worst topic across all subjects; pain in the ass. Just don't understand it very well; even with the explanation you've just given me. There's a whole subject called "electronics" don't see why they don't just leave it in there, instead of tying it in with Physics.

Anyways (thinking positive), as far as I'm aware I've got 22/25 in the multiple choice, so here's hoping my unlooked-over section 2 paper is enough to get me an A lol. I'm actually crapping myself, still in awe at misinterpreting the time...

I’m sure you’ll have done fine, you have your assignment too so I wouldn’t worry

But in this circuit vs=v1 + v2 + v3 so I got a because only the second statement was right or am I just wrong ?

(Original post by Fhhdndjdj)
In a series circuit vs=v1+v2 in parallel voltage is the same at every point

you've probably done great, I wouldn't worry about it so much. If you can identify your mistakes you probably know how to improve and know for next time. I honestly found the whole paper *******s so I'm sure many others did too, lowing grade boundaries.

In this circuit I dont think it does because V2 and V3 are in parallel.

Oh yeah but then it wouldn’t equal v1 plus v2 anyway so I’m still confindent that it is a

Yeh, the assignment was easy, I'm hoping for full marks in that; as I'm sure a lot of people are too. Overall, that gives me like 2 more marks extra to ensure I stay at my dedicated grade.

It's not necessarily mistakes, it's just confusion in times. Our school, for some reason, doesn't announce what time the exam finishes either, which is ridiculous. And true, grade boundaries can be lowered as well, so that does give more space.

Anyways thank you both for your reassurance .

Also, do the SQA still do Band-A grades? Like Band-A-2 = 75%-85% and Band-A-1 = 85%-100%, and if they do, do they show up on your report card as regular A's or with something special to identify them?

I know that they calculate the "upper A" grade but I dont know if they actually award them and if they show up on certificates and reports.

University’s are not able to find out if it is an A1, in other words an A is an A
