Web(a) In a meter bridge the balance point is found to be at 39.5 cm from the left end A, if an unknown resistor X is in the left gap and known resistor Y of resistance 12.5 Ω is in the right gap. Determine the resistance of X. Why are the connection between resistance in a Wheatstone or metre bridge made of thick copper strips ? WebIn a meter bridge, the balance point was found to be at a distance of 25cm from the zero end when two resistances were placed in its two gaps. When a series resistance of 5 Ω is connected with the smaller of the two resistances, the balance point is shifted 50 cm from the zero end. The resistance of the two wires is R = 2.5 Ω and S = 7.5 Ω

WebA pontoon bridge (or ponton bridge), also known as a floating bridge, uses floats or shallow-draft boats to support a continuous deck for pedestrian and vehicle travel. The buoyancy of the supports limits the maximum load that they can carry.. Most pontoon bridges are temporary and used in wartime and civil emergencies. There are permanent pontoon … WebApr 11, 2024 · The right lane of eastbound I-64 on the lower deck is scheduled to be closed on or after 6 p.m. Friday until 1 p.m. Saturday or until crews finish the ordering instructions ks1

WebD G B l 1 100 l 1 3.11 In a meter bridge the point D is a neutral point (Fig 3.3). (a) The meter bridge can have no other neutral point for this set of resistances. (b) When the jockey contacts a point on meter wire left of D, current flows to B from the wire. (c) When the jockey contacts a point on the meter wire to the right of D, current ... WebDec 4, 2015 · (ii) In the meter bridge experimental set up, shown in the figure, the null point D is obtained at a distance of 40 cm from end A of the meter bridge wire. Ans. 34. (i) Use Kirchhoff’s rules to obtain the balance condition in a Wheatstone bridge. WebMay 26, 2016 · A meter bridge is an apparatus used to find the resistance of a coil; you will find it as part of the tools of a physics lab. Steps 1 Check that the meter bridge wire is connected. If not, just connect both ends of the wire tightly. The apparatus has 5 places for the connections. ireps pki component not yet initialized
