WebJan 17, 2024 · A meter bridge is set-up as shown, to determine an unknown resistance X using a standard 10 ohm resistor. The galvanometer shows null point when tapping-key is at 52 cm mark. The end-corrections are 1 cm and 2 cm respectively for the ends A and B. The determined value of X is (a) 10.2 oh (b) 10.6 ohm (c) 10.8 ohm (d) 11.1 ohm WebJan 31, 2024 · Once the galvanometer shows zero deflection from its null point we take the position of the sliding contact tip on the resistor scale. Say this is L 1. Now we make the switch on. At that condition, a circulating current starts flowing through the battery cell as well as the resistance (R). As a result, there is a voltage drop in the battery ...
WebJul 4, 2024 · A galvanometer is an electromechanical measuring instrument used to detect strength and direction of the electric current in a circuit. Symbol: Measuring quantities: An ammeter can measure only the magnitude of electric current. A galvanometer can show the magnitude as well as direction of the current in the circuit. Zero position WebThis is the bridge balance condition. Only under this condition, galvanometer shows null deflection. Suppose we know the values of two adjacent resistances, the other two resistances can be compared. If three of the resistances are known, the value of unknown resistance (fourth one) can be determined. EXAMPLE 2.23

WebThe p.d. across XY is decreased and the balanced length XN is increased. 83. In the potentiometer circuit below, the moveable contact is placed at N on the bare wire XY, such that the galvanometer shows zero deflection. The resistance of the variable resistor is now increased. What is the effect of this increase? laluletteWebWith switches Si and S2 closed, these resistors are varied until the current in the galvanometer G is zero; the bridge. 26.74 If the galvanometer G shows zero deflection when M=840.0 (omega), N=14.00 (omega), and P=33.38 (omega), what is the unknown resistance X?
