WebIn a meter bridge, the null point is found at a distance of 33.7 cm from terminal A (known resistance R is connected to gap near to A). If a resistance of 12 Ω is connected parallel to unknown resistance X (which is connected to gap near to terminal B), the null point is found at 51.9 cm. The value of X is Q2. WebIf the null point is in the middle of the meter bridge, then only P, Q, R, and S will become equal and the bridge will become more sensitive and will give more accurate results. …
[Solved] In a meter bridge, the null point is obtained at a distance
WebA Meter bridge is used to calculate resistance values with high accuracy. ... can say x the resistance of the banana equals r times l we call this the balancing length we also sometimes call it the null point because this is the point where there is no current flowing through so null point divided by divided by what is that um r into l divided ... WebMay 9, 2024 · For the accurate measurement of resistance by metre bridge, the null point should be obtained. asked Apr 18, 2024 in Physics by Somyek (121k points) class-12; current-electricity; 0 votes. 1 answer. When a metal conductor connected in the left gap of a metre bridge is heated, the null point ... super flexible chimney rods
In a meter bridge with R and S in the gaps.the null point is …
WebIn a meter bridge, there are two unknown resistance R 1 and R 2. Find the ratio of R 1 and R 2 if the galvanometer shows a null deflection at 30 cm from one end? Solution: The null deflection in the galvanometer is given … WebApr 9, 2024 · A meter bridge is used in finding the unknown resistance of a conductor as that of in a Wheatstone bridge. The reason why this bridge is called the Meter Bridge is … WebIn a metre bridge experiment, null point is obtained at 20 cm from one end of the wire when resistance X is balanced against another resistance Y. If X < Y, then where will be the new position of the null point from the same end, if one decides to balance a resistance of 4X against Y?
