Question

12 A potentiometer circuit is set up as shown. The
value of k is 0.025 V/cm and the ammeter reads
0.1 A when the two way key is totally switched off.

The balance points of the circuit for the
connections: (1 and 2) and (1 and 3), are 40 cm
and 100 cm respectively. Find the values of R and
X.
