How much are u expectin in Physics ???

[sachinsethi]

hey i knw u don't want to recollect those memories.. but i just wanted to knw how i did in comparision to others !!!

[pkciit]

i am expecting 50-55

[pkciit]

the ratios i got were 1:2 and 2:1

[farheen]

YEA..WAS A MINDBLOWING XAM-LITERALLLY
NYWAYZ MAYB 55-60'S..DEPENDS ON TE WAY THE EXAMINER CORRECTS THOUGH
NYWAYZ GUD LUCK PPL!

dunno how u got the second result mate..

see... for second case !
area of first wire = A
area of second wire = 2A

if for wire 1, the resistance is = R
then for wire 2, resistance is = R/2

when connected in parallel... current across wire one = I/3
current across wire 2 = 2I/3 (becuase of ratio of resistances.)

then
v = I /(neA)

v1 = I/(3neA)
v2 = 2I/(3ne2A) = I/(3neA)
