    When the two known resistances RR and SS are connected in the left and right gaps of a meter bridge respectively, the null point is found at a distance l1l_1 from the zero end of a meter bridge wire. An unknown resistance XX is now connected in parallel with SS and null point is found at a distance l2l_2 from zero end of meter bridge wire. The unknown resistance XX is
