Uses of Potentiometer | Comparison of emf of two cells using Potentiometer || Class 12, JEE & NEET
The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential (voltage); the component is an implementation of the same principle, hence its name. Potentiometer are commonly used to control electrical devices such as volume controls on audio equipment. We will study here about Comparison of emf of two cells using Potentiometer, Determination of internal resistance of cell, Calibration of voltmeter, Calibration of ammeter, Measurement of sm...
Read More →Sensitivity of Potentiometer - Current Electricity || Class 12, JEE & NEET
Sensitivity of Potentiometer means the smallest potential difference it can measure. It can be increased by reducing the potential gradient. A potentiometer is sensitive if it is capable of measuring the small potential differences and it shows significant change in balancing length for a small change in the potential difference being measured. Sensitivity of Potentiometer means the smallest potential difference that can be measured by using it and this can be achieved by decreasing the potentia...
