umm in O/N 07 5 b(ii)..how use the area below the graph to determine the intial charge stored int he capacitor

count the small boxes under the graph (half, n more than half counts as 1 box)
find area of 1 box, n multiply it with number of boxes. thats ur area

@ jazib
then ull do only this question in the exam
just do it by finding are under the graph making as many small divisions as possible and there's a range!

 

[Jazib]

@ zahra, im comfortable with this method, takes only 3-4 mins doin this question. i did 2 of em (which i found in past papers) n i think u took that wrong, by 1 small box, i mean a centimeter box.

My physics sir recommends the same method. Of counting boxes. It gives a more accurate answer.

 

[Jazib]

n the name of that sir wud b?
Sulehri! He rox.

 

[Vnza]

Lol no. Sir Akhter. Are you in Sicas? I think Sulehri teaches there.
