A potentiometer is an accurate and versatile device to make electrical measurements of E.M.F, because the method involves:
- Cells
- Potential gradients
- A condition of no current flow through the galvanometer
- A combination of cells, galvanometer and resistances
Solution
Reading of potentiometer is accurate because it doesn't draw any current from the circuit while measuring the voltages.
