WebIn a meter bridge experiment resistance are connected as shown in the figure. Initially resistance P=4 and the neutral point N is at 60 cm from A. Now an unknown resistance R is connected in series to P and the new position of the neutral point is at 80 cm from A. The value of unknown resistance R is : Option 1) Option 2) Option 3) Option 4) WebJun 9, 2024 · Ans.(d) 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. WebA 3-phase, 4-wire Delta system that has a circuit conductor that connects to the midpoint of one of the phase windings In other words, if it is likely that a system will be supplying 120V or line to neutral loads, it will need to be grounded unless specifically permitted or required to not be grounded by 250.21 or 250.22.
