Last updated: 6/20/2023

Circuit for the measurement of resistance by potentiometer is shown The galvanometer is first connected at point A and zero deflection is observed at length P J 10 cm In second case it is connected at point C and zero deflection is observed at a length 30cm from P Then the unknown resistance X is nR fill the value of n P www R ww A M
