If the unknown Resistancee calculated without using the end correction is `R_(1)` and with using end corrections is `R_(2)` then (assume same end corection) .

Options

A. `R_(1)gtR_(2)` when balanced point is in first half
B. `R_(1) gt R_(2)` when balanced point is in first half
C. `R_(1) gt R_(2)` when balanced point is in first half
D. `R_(1) gt R_(2)` when balanced point is in first half

Explanation

`R_(1)=S((l)/(100-l))R_(2)=S((l=alpha)/(100-l+beta))`
If balance point is in first half say `1 =40`
`R_(1)=S((40)/(60))R_(2)=S((41)/(61))soR_(2)gtR_(1)`
If balance point its is in second half say `=70`
`R_(1)=S((70)/(30))R_(2)=S((71)/(31))soR_(2)ltR_(1)` .
