Wasn't it C?

I put C too

Yo ppl!! What did u guys get 4 d strain enery? was it 0.066J ? So how did u all find the paper overall?

 

[sarahh maria]

yes it was C
GUYS THE EXPERIMENT did you put a power supply and kept changing the voltage and noting the current or something

yes it was

 

[Zitayyyyy]

for the graph for the last question, wasn't the scale messed up? i ended up using graph paper instead hahaha and i got a value of the strain energy as like 0.076J =p is it still valid? my graph was a straightline but i made it curve right at the end not sure if its right but yeah and for q1 mcq i swear you include the anomalies aswell =p

I drew a circuit diagram including : Voltmeter, Ammeter , Variable resistor and a power supply. i mentioned that i started the rheostat at max setting to reduce heating effects and gradually lowered it, recording corresponding values of P.D and Current

where did the 3.5 battery fit into this and for mcq 1 no i asked my physics teacher in this case you ignore the .42 it was too large of a difference from the others

Oh haha i forgot about battery, ya you connect a voltmeter parallel to the cell and an ammeter in series to the cell. As you change the settings on the rheostat, the readings tell you how much current and voltage is being supplied to the cell being supplied to the battery. Damn i got 1st question wrong.. great..

I think i just about got an A. I think i lost marks on the last question and the emf question but thats it Hopefully all will be good. I have never taken edexcel before btw how does this work? do our online results contain a mark for each paper?

 

[azraial031]

can any one tell me wat came on the question paper....how many questions came???? and wat type of questions for physics unti 3
