In the experiment of potentiometer wire $A B$ is 100 cm long shown in figure When AC=40 cm, no deflection occurs in the galvanometer. What is the value of R ?

Consider the potentiometer circuit shown. The potentiometer wire is 600 cm long and having restance 15r At what distance from the point A should the jockey touch the wire to get zero deflection in the galvanometer?

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 PJ=10 cm. In the second case, it is connected at a point $C$ and zero deflection is observed at a length $30 text end text c m$ from P. Then what is the unknown resistance X?

The current taken from the 30 V supply and the current through the 6 $capital omega$ resistor are respectively.
