Answer 2

Answer:

(a) condition for balanced wheatstone bridge,

YX=l1100−l1

X=8.2Ω

To minimize the resistance which is not taken into formula.

(b) if X and Y are interchanged then balance of bridge will be at 100−39.5=60.5 cm from A.

(c) Since the bridge is balanced, there will be no difference if position of cell and galvanometer are interchanged as there will be no flow of current from galvanometer.
