Potentiometer is a device used to measure emf, internal resistance of device. It is also used to measure PD between any circuit element which is more accurate as comapred to the PD measured from Votmeter

The Potentiometer is an instrument used for the measurement of potential difference . It consists of a ten metre long uniform wire of manganin or constantan stretched in ten segments, each of one metre length. The segments are stretched parallel to each other on a horizontal wooden board. The ends of the wire are fixed to copper strips with binding screws. A metre scale is fixed on the board, parallel to the wire. Electrical contact with wires is established by pressing the jockey J.

A potentiometer is a simple knob that provides a variable resistance, which we can read into the Arduino board as an analog value.
example, that value controls the rate at which an LED blinks.

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
