- How can we make potentiometer more sensitive ?
- What is the material of potentiometer wire ?
- Which type of driving cell is used in main circuit ?
- State the underlying principle of potentiometer ?
- What are the factors on which the sensitivity of potentiometer depends ?
- Why is resistance used in series with Galvanometer ?
Such questions must come to your mind for understanding the concept
