Why we used KHP for the standardization of potentiometer??
1 Answer
Vikas TU
Standardization of a potentiometer is done by connecting a standard-cell to the terminals marked “Standard-Cell”, Galvanometer and Battery to their respective terminals. Potential dials are set to the effective voltage of the standard cell. Now by pressing “Standardize” key and adjustingbattery Rheostats (coarse and fine) balance is obtained. The galvanometer should show no deflection with standardized key pressed and zero series resistance. Then the potentiometer is said to be “standardized”.

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
