In a meter bridge experiment the ratio
WebA jockey (conducting wire) is connected to the terminal E on the central copper strip through a galvanometer (G) and a high resistance (HR). The exact position of jockey on the wire … WebIn a meter bridge experiment S is a standard resistance, R is a resistance wire. It is found that balancing length is l=25 cm. If R is replaced by a wire of half length and half diameter of that of R of same material, then the balancing l in cm will now be: In a meter bridge experiment S is a standard resistance, R is a resistance wire.

WebJun 9, 2024 · 34.Statement – 1 : In a Meter Bridge experiment, null point for an unknown resistance is measured. Now the unknown resistance is put inside an enclosure maintained at a higher temperature. The null point can be obtained at the same point as before by decreasing the value of the standard resistance. 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.
WebIn a meter bridge experiment, null point is obtained at \( 20 \mathrm{~cm} \) from one end of the wire when resistance \( X \) is balanced against another re... WebA meter bridge is balanced by putting 20 2 resistance in the left gap and 40 12 in the right gap. If 40 12 resistance is now shunted with 40 12 resistance, the shift in the null point towards right is nearly (a) 16.67 cm (b) 50 cm (c) …

The sensitivity with ratio P/Q = R/S = 1000 would be about 1/250 of that for unity ratio. The sensitivity with P/Q=R/S=1000 would …
WebJan 2, 2024 · With resistances X and Y ohm in left and right gaps respectively of a metre bridge, the point is obtained at 30 cm from the left of the wire. When Y is shunted with 15 Ω resistance, the shift in null point is 10 cm. Solution: Case – I: Given: resistance in left gap = X Ω, Resistance in right gap = Y Ω, l = 30 cm and, 100 – l = 100 – 30 = 70 cm
