Potentiometer is an apparatus used for measuring the emf of a cell or potential difference between two points in an electric circuit accurately. Circuit diagram and working of potentiometer answers A circuit diagram is a representation of an electronic circuit in a drawing form. Each electronic component is represented by a symbol and usually some text describing exactly what it is. Read More Important Questions for CBSE Class 12 Physics ... The circuit diagram of potentiometer for determining internal resistance of a given cell is shown Measurment of Internal Resistance of a Cell Using Potentiometer 27.Two cells of emf E x , E 2 and internal resistances r a and r 2 respectively are connected in parallel as shown in the figure. The Potentiometer And Wiring Guide Build Electronic Circuits We call the middle pin the wiper. It is connected somewhere on the strip between the two ends. You can move the point where the wiper connects to the carbon strip by turning the shaft of the potentiometer. When you move the wiper to the left side, the resistance between the middle pin and the left pin decreases. how to make circuit diagram of potentiometer? | Yahoo Answers You can refer to Physics Theory XII in my free educational website listed below which I have launched as a part of my hobby where you will find the circuit diagram of a potentiometer and its use to measure emf of a battery.
