WebMar 24, 2024 · The resistance x, R resistance of L 1 length of wire and resistance of 100 - L 1 length of wire from the resistances of wheatstones bridge. As the meter bridge wire is … WebAug 24, 2024 · Metre Bridge: Special Case of Wheatstone Bridge It is a practical device based on the principle of Wheatstone bridge to determine the unknown resistance of a wire. If ratio of arms resistors in Wheatstone bridge is constant, then no current flows through the galvanometer (or bridge wire).
In a meter bridge experiment, the ratio of the left gap
WebAt this point, the bridge is said to be balanced. CALCULATION: Given: In first case balance point is at 25 cm from the zero end According to the Wheatstone bridge principle (which is the foundation of meter bridge), ⇒ R S = P Q For the first balanced bridge situation, ⇒ R S = P Q = 25 75 = 1 3 where R and S are the two unknown resistances WebMeter-bridge is a sensitive device based on the principle of Wheatstone’s bridge, for the determination of the resistance of a conductor (wire). Meter-bridge is shown in Figure. AC is a 1-meter wire of manganin or constantan which is fixed along a scale on a wooden base. The area of cross-section of the wire is the same at all places. soft wool area rugs
Meter Bridge: Principle and Working Experiment - Embibe
WebMake sure that the pointer of the galvanometer deflects towards opposite directions when you make the contact between the jockey and the meter bridge's wire near end-A and end-B. 2) Choose the values of P and Q, and make sure that they are not equal. Calculate r = P/Q. 3) Put the plugs in the commutator to connect (w, y) and (x, z) terminals. WebTurn on the DC power supply and adjust the voltage knob for some intermediate value. Set the dial on the potentiometer to the 5.00 reading. Depress YEY 1, 5 VOLTS button on the galvanometer. Pull and replace the plugs on the resistance box until the galvanometer needle is zeroed or nearly zeroed.
