Two diametrically opposite points of a metal ring are connected to two terminals of the left gap of meter bridge. The resistance of 11 Ω is connected in right gap. If null point is obtained at a distance of 45 cm from the left end, find the resistance of metal ring.
R = 11Ω , lx = 45cm
Let x be theresistance of metal ring
∴Equivalent resistance in left gap
From balancing condition
