Question

2) Two resistances of 40 Ω & 60 Ω are connected in right gap & left

gap respectively in meter bridge. Calculate null point from left end.

Also calculate shift in null point when

i) both resistances are shunted with resistance of 10 Ω each

ii) resistance of 10 Ω is connected in series with each resistance​
