I'm pretty bad too in the prelim I got 2 out of 3 and 1 out of 3
Dont worry, in the prelim i got 0 for both

I'm pretty sure it said How are different voltages and currents obtained ?

Correct me if Im wrong ...
What did you write anyway ?
I spoke about ohms law and how voltage and current are directly proportional. I don't think I answered it correctly
3. (Original post by 12345kiran)
I talked about changing the resistance of the variable resistor
How many marks was that question ?

Going by the way you answered it I think i have gotten it all wrong

For one of the early questions

where it gave you 4 voltages and 4 currents ( I think)
and then it asked you to find the resistance, what did you guys do with the figures in the table ?
I added all the voltage values together. Then I done the same with the current values and then done R=V/I and got 5

Yeah I did that too and I also said how he could calculate averages or something
I was gonna write averages

Your invigilators suck! Everyone (nearly) takes the paper in our school.

Photosynthesis...? *MAJOR FACEPALM

BLOODY HELL!?!? 90/110!?!??!?!?!
Haha dont worry, i probably lost 10 or so marks from stupid mistakes

My exams are now over. I can officially sit and play call of duty all day until further notice

I got the same tooo 5 ohms, Got an average Voltage and an Average current

1 mark.

I mentioned increasing or decreasing the resistance, But never mentioned the variable resistor. I was going to, But I left it out :/ do u think I'll still get the mark?

I got 5 ohms. But the question said use all the values in the table for some odd reason so i calculated the resistance four times and I got 5 ohms for all of them

Yeah if you found an average for both voltage and current it gives you 5 ohms also. I think that's what they mean too
10. Really scared for results day

Yeah I never thought of it that way lol

Wait i found the averages for both current and voltage and plugged the numbers in the equation do I get the marks PLS HELP THAT WAS 4 MARKS IM STRESSING AKABSHDKF

Same, For the prelims getting one result from a subject was pretty scary... Getting them all at once is something else, haha

Still got 5 ohms tho, But your method seems more correct.

Can u remember ur values for v and i???

It was either 3 or 4. I would say 4 because you needed to use the values of each table but I don't know because some people picked one voltage and one current from each table and still got the same answer

But it said using all of the values from the table?

Exactly, that's what making me believe it was 4 Marks
19. I wish i had photographic memory so i could just remember my entire paper and calculate to what extent i failed

It was 4 marks yeah. i can remember it clearly being 4
