A potentiometer is an accurate and versatile device to make electrical measurements of EMF because the method involves potential gradients a condition of no current flow through the galvanometer a combination of cells galvanometer and resistances cells
Multiple Choice Options
- A potential gradients
- B a condition of no current flow through the galvanometer
- C a combination of cells, galvanometer and resistances
- D cells
Step-by-Step Verified Solution
A potentiometer is an accurate and versatile device to make electrical measurements of E.M.F. because the method involves zero deflection without any current in galvanometer.
