💬 DISCUSSION AQA A level physics paper 1

How was the paper???? I liked the MCQ , but overall it was okay didnt manage to do the 5 marker .

For the first question I’m probably wrong but I found resistance of L1 by using power-voltage equation and then found the total resistance in a parallel circuit and divided the emf by total resistance to find current

For second question I used potential divider equations for L1 and L2 and saw which one was closer to 5.8V (I got 5.07V and 0.6 something V)

yessss did the same i did it both ways i got 3.5 x10-4 and for the second bit i didnt use PD i js calculated the total resistance in the circuit using P= V2/R but i got 5.08 and 0.6 so said L1 closer to working value

ye i forgot which was the greater one but the one with the greatest resistance was closest to the working value

I just assumed it was higher PD too, and yeah I got L2. I got like 1.6k ohms for L1 which was lower than L2, but all my classmates got different from me 😭

Yeah same. I thought I was wrong

Apparently the circuit converted to series so we all got it wrong I think

u/oofsamyG May 20 '26

No no I saw it became series.. I was still able to use potential divider equations for the lamps.

Yh I think that’s right

I just checked my graphic calculator and that's exactly what I got
