The full scale value should be the minimum whole value which can offer good linearity and accuracy

I see, I get what you mean.
Heres another:
The pic. shows identical lamps X adn Y in series. The lamps are at normal brightness. A third lamp Z is connected in parallel to X.
What happens to the brightness of lamp y ?

falls
nid404:
Decrease..
Since current through the lamps X n Y decrease...current splits in a parallel circuit

Even I said that !!!!!
My answer booklet (not the real Markscheme) says it will become BRIGHTER THAN NORMAL..... -_-
Stupid answer booklet... >:(
Amr Fouad:
The brightness of lamp Y decreases...
Now, X and Z are connected in parallel, and BOTH are in series with Y..
