WebNull point in potentiometer: A null point in a potentiometer is also called a balancing point. It is the point on the slide wire where the deflection is at zero by the galvanometer. When the galvanometer detects the current where the deflection is at zero, there will be no current flowing through the cell. WebPotentiometer is a device used to compare the emfs of two cells. (or) to find the emf of a cell (or) to find the internal resistance of a cell (or) to measure potential difference. Construction: A potentiometer consists of uniform wire of length 10m arranged between A and B as 10 wires each of length 1m on a wooden board. can your face change from stress

Web(1) 2 H + ( aq) + 2 e − ⇌ H 2 ( g) and the half-cell potential arbitrarily assigned a value of zero (E 0 = 0.000 V). Practical application of the SHE is limited by the difficulty in preparing and maintaining the electrode, primarily due to the requirement for H 2 (g) in the half-cell. WebA potentiometer is a resistive-type transducer that converts either linear or angular displacement into an output voltage by moving a sliding contact along the surface of a resistive element. Figure 10.12 illustrates linear and angular-type potentiometric transducers. A voltage, Vi, is applied across the resistor, R. bring your own phone metropcs
