Circuit for the measurement of resistance by potentiometer is shown. The galvanometer is first connected at pointA and zerodeflection is observed at length PJ=10 cm. In the second case, it is connected at a point and zero deflection is observed at a length from P. Then what is the unknown resistance X?
