The error is cannot exceed the L.C . See you to understand this you need an example .
Consider a Meter sclae
L.C = 0.1cm
Hence if the result is 2.7cm
You may read it as 2.8 or 2.6 . i.e the variance from the result will only be by ±1 L.C
wats max error in measurement generally ?
L.C or half of L.C
different buks gve different ans wats the right one ?

9but in my practical notes its gvn as half of LC as for LC .1 , measurment of 2.7 means 2.65 to 2.55 ie error of .05 up and down
9Nishant bhaiyya i ve never seen a postoffice box
what are its principles ?
pls help
9yes but wrt to the fig above how can u explain ??
this is a jee q
13CB=R1
BA=R2
CD=R3
AD=unknown R
DC'=Galvanometer
AB'=e.m.f source
oops sorry
1There's a small error in ur answer abhirup.!
AC' = emf and DB' = galvanometer. only then it forms a wheatstone bridge. and the unknown resistance must be connected b/w A & D itself.
