Runk*560=100*1232=220 ohm
runk*r1=r2*r3
runk*r1=r2*r3

In order to balance the bridge the product of opposite resistors must be equal.
i.e; Runk x R1 = R2 x Rv
i.e; Runk x R1 = R2 x Rv

In order to balance the bridge.
560/(560+100) = 1232/(1232+R).
So R = 220 ohm.
560/(560+100) = 1232/(1232+R).
So R = 220 ohm.
