Question

The minimum and maximum values of the temperature are 305 k and 627 k and the entropy 1.23 kj/k and 2.85 kj/k respectively. the cycle efficiency is

Answer 1

Sensitivity of potentiometer can be increased by. Sensitivity of potentiometer can be increased by increasing the length of the potentiometer wire and by reducing the current in the circuit by using a rheostat. Both the methods help in decreasing the potential gradient, and thereby increasing the resistivity.
