WebThe aim of this experiment is to verify the laws of the parallel combination of resistance using a meter bridge experiment. There are two resistances R 1 and R 2. When connected in series, the resistance combination R 1 is given by: RS= R 1 +R 2. The experimental value of X p = ohm. The theoretical value of X p = ohm. 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 …
WebNov 10, 2024 · A meter bridge works on the principle of a Wheatstone bridge. A Wheatstone bridge is based on the principle of null deflection, i.e. when the ratio of resistances in the two arms is equal, no current will flow through the middle arm of the circuit. Consider the diagram of the Wheatstone bridge as shown below. 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.
Webthis experiment. You can also do step 1 in the Wheatstone Bridge section. Background The Wheatstone Bridge circuit can be used to measure an unknown resistance in terms of three known resistances by adjusting one or more of the known resistors to obtain a zero signal (i.e. a \null" reading) on a meter. Such a measurement permits high precision ...
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) … high strength lightweight steelWeb2 days ago · Barnum Channel Cable Bridge Construction: n/a: Q4 2024–Q2 2025. ...
