Write balancing condition of a Wheatstone bridge.

थोडक्यात उत्तर

उत्तर

When no current flows through the galvanometer, the wheatstone bridge is considered to be in a balanced state. This condition can be met by modifying the known and variable resistance.

The balancing condition,

`"R"_1/"R"_2 = "R"_3/"R"_4`

State any two sources of errors in the meter-bridge experiment. Explain how they can be minimized.


In a meter bridge, the balance point is found to be at 39.5 cm from the end A when the resistor R is 12.5 Ω (right gap).

a) Determine the resistance of X (left gap).

b) Determine the balance point of the bridge if X and R are interchanged?

c) What happens if the galvanometer and cell are interchanged at the balance point of the bridge?


A resistance of 5 `Omega` is connected in the left gap of a metre bridge and 15 `Omega` in the other gap. The position of the balancing point is ____________.


In a balanced metre bridge, 5 Ω is connected in the left gap and R Ω in the right gap. When R Ω is shunted with equal resistance, the new balance point is at 1.6 I1 where 'I1' is the earlier balancing length. The value of 'I1' is ______ 


In the meter bridge experiment, a null point was obtained at a distance of ℓ from the left end. The values of resistances in the left and right gaps are doubled and then interchanged. The new position of a null point is ______


In a metre bridge experiment, the ratio of the left-gap resistance to right gap resistance is 2: 3. The balance point from the left is ______.


The current through 1 `Omega` resistance in the following circuit is ______. 


If in the experiment of Wheatstone’s bridge, the positions of cells and galvanometer are interchanged, then balance point will ______.

The measurement of an unknown resistance R is to be carried out using Wheatstones bridge (figure). Two students perform an experiment in two ways. The first students takes R2 = 10 Ω and R1 = 5 Ω. The other student takes R2 = 1000 Ω and R1 = 500 Ω. In the standard arm, both take R3 = 5 Ω. Both find R = `R_2/R_1 R_3` = 10 Ω within errors.

  1. The errors of measurement of the two students are the same.
  2. Errors of measurement do depend on the accuracy with which R2 and R1 can be measured.
  3. If the student uses large values of R2 and R1, the currents through the arms will be feeble. This will make determination of null point accurately more difficult.
  4. Wheatstone bridge is a very accurate instrument and has no errors of measurement.

A resistance of 20 Ω is connected in the left gap of a meter bridge and an unknown resistance greater than 20 Ω is connected in the right gap. When these resistances are interchanged, the balance point shifts by 20 cm. The unknown resistance is ______.
