acha pehlay to i cant be a gud boy coz em a girl :p :p :p
second thing is that i have not drawn graphs of three papers n u r askin about thingx from those lol....
but i know how to find this error....i wax just busy with maths so i am too lazy to draw graphs now...

anyway for your s.f confusion. use the d.p or s.f in the table by referring to the axis of the graph. c how many they have used that would be helpful...
and for uncertainities beter if u use 2 d.p or 3 s.f ...

idk if anyone else replied to this,.. anyways, u should just say, Use a wide range ohmmeter/ammeter/whatever
and oh really imp
wen ur drawing circuits keep in mind::
OHMMETER DOES NOT REQUIRE POWER SUPPLY..

yaar coz c the graph u can easily plot points of 3 to 4 sig fig.

v round of our numbers so dat v can easily plot the numbers in the axis ALREADY given to us...so luk at it u can easily plot these...besides rounding off to 2 d.p will decrease the accuracy of ur graph!!!

SHOULDNT WE RITE it as 2.79+- .01

graph main jo bhi absolute errors nikaltay hain na try to write them in atleast 3 d.p for accuracy. in graph it doesnot matter k u have used how many d.p.

P.S just for the sake of accuracy do not try to round off numbers more.!!! this will always help u in gettin exact answers.!!!
