Sahay Sir > Question Answers > then the unknown resistance X is .
Circuit for the measurement of resistance by potentiometer is shown in figure. The galvanometer is first connected at point A and zero deflection is observed at length PJ=10cm. In second case, it is connected at point C and zero deflection is observed at a length 30 cm from P, then the unknown resistance X is .
