Instead of being a voltage controller, the potentiometer will work as current controller or a rheostat. << As such it will be used in experiments to adjust resistance within a circuit to fine tune or derive precise values. The ammeter reading should remain constant for a particular set of observation. Again slide the jockey along the potentiometer wire to obtain the null point. /Type /XObject Ensure the current is passed only while obtaining the null point. A resistance box is a rheostat, a device meant to maintain specific electrical currents. /Filter /FlateDecode � Slide the jockey along the potentiometer wire and obtain a null point. Ensure that all connections are tight, make sure the components are functional and clean, use a DC supply with low voltage (to minimize potential hazards), make sure the power supply has a rating nearly equal to the lamp or bulb, make sure ammeter is in series and voltmeter is in parallel, etc. /BitsPerComponent 1 Practically these are used in fans regulators. /Type /Group /Height 1894 /Interpolate true A jockstrap consists of a waistband, usually elastic, as well as a support pouch for the genitals. /Subtype /Form IF I am thinking of the same jockey circuit as you, it is in effect a rheostat (basically a variable resistor) that provides very low but very accurate resistance. Without inserting the plug in the key adjust the rheostat so that a null point is obtained on the 4th wire of potentiometer. >> We use this relation (E 2.1) to determine S if P, Q and R are known. 3 0 obj The potentiometer is most sensitive when, at the balancing point, the slider or jockey is towards, but not too close to, the end of the potentiometer wire.

Although a potentiometer is a three-terminal device — its leads connect to the wiper and to both ends of the resistance track — you can use a potentiometer as a rheostat (as is quite common) by connecting only two of its leads, or you can connect all three leads in your circuit — and get both a fixed and variable resistor for the price of one! /ColorSpace /DeviceGray endobj �,,��l��u��4)\al#:,��CJ�v�Rc���ӎ�P4+���[��W6D����^��,��\�_�=>:N�� : higher the resistance lower is the speed of fan. >> /Filter /FlateDecode Circuits. endstream /Type /XObject /Length 50 When two resistances R 1 and R 2 are connected in series, the resistance of the combination R S is given by R S = R 1 + R 2 When connected in parallel, the resistance R P In primary circuit the rheostat (Rh) is so adjusted that the deflection in galvanometer is on one side when jockey is touched on wire at point A and on the other side when jockey is touched on wire at point B.The jockey is moved and touched to the potentiometer wire and the position is found where galvanometer gives no deflection. /Type /XObject /ExtGState The positive terminal of the cell of e.m.f.

Insert the 2000 ohm plug back in the position in resistance box and by slightly adjusting the jockey near the previous obtained position of null point, obtain null point position accurately, using a set square. Make sure that the reading on the ammeter is constant throughout the observation. /CA 1 To obtain the null point on the fourth wire, the rheostat should be adjusted without inserting the key K 2.
