A potentiometer is a measuring device that can be used for measuring unknown resistance, voltage, and power in a circuit. Other than this a potentiometer application includes calibration of various measuring instruments like volt…
Construction of Duo-range Potentiometer : The duo-range potentiometer is the modified version of Crompton's dc potentiometer with an extended range selector. The construction and connection of a Duo-range Potentiometer is sh…
A potentiometer is a device that measures the value of an unknown voltage. The working principle is based on the comparison of an unknown voltage with a known voltage. Potentiometers are the most commonly used devices for measure…
The various applications of ac potentiometer are, Calibration of voltmeter Calibration of ammeter Calibration of wattmeter Measurement of self reactance or inductance of a coil. Calibration of Voltmeter : The circuit diagram fo…
What is an AC Potentiometer? An ac potentiometer measures the unknown ac voltage or emf similar to dc potentiometers used for measuring dc voltage. The balance condition is obtained when the unknown voltage is equal to the drop …
AC Polar Type Potentiometer : The Drysdale Tinsley AC Potentiometer is a polar-type potentiometer, which measures the magnitude (V) in one scale and phase (θ) in another scale. The complete connection diagram of the Drysdale Tin…
A coordinate type potentiometer is a combination of two potentiometers. One of the potentiometers carries a current in-phase with the supply voltage and it is called an 'In-phase Potentiometer'. The other potentiometer ca…
A potentiometer is a device used for measuring the emf of a cell or potential difference between two points in a circuit. It works on the principle of comparison i.e., comparing the unknown voltage with the known voltage and make…
