The galvanometer circuit includes a set of compensating resistors R 1R 2. The combination of dial resistors and the slide wire is set to the standard cell voltage. The following steps are used when making measurements with the above potentiometer: The standardising circuit may be checked for the constancy of working current, anytime during the measurements by simply throwing the switch S back to calibrate position. Single range potentiometer using independent calibrating circuit. DC POTENTIOMETERĭuo range type potentiometer. Our company is devotedly engaged in supplying a wide assortment of Crompton Potentiometer that is designed using the latest technology. This process does not disturb the measuring circuit while convenience and speed of measurements are increased. This completes the standardisation process for the potentiometer. The standardisation of the potentiometer is checked again by returning the switch S to the calibrate position. The slide-wire type ptentiometer potentiometer described in the previous article is not a practical form of construction. This instrument has two ranges: I agree to the terms and privacy policy. The switch S is thrown to the calibrate position and the galvanometer key is tapped while the rheostat is adjusted for zero deflection on the galvanometer. AC Potentiometers.ĭw crompton potentiometer pdf télécharger The slide-wire type of potentiometer described in the previous article is not a practical form of construction. Crompton Potentiometer complete setup for physics experiment.
