    Meter Bridge |Question practice

    In a meter bridge, the length of the wire is 100 cm. At what position will the balance point be obtained if the two resistances are in the ratio 1:3?

    When two known resistance R and S are connected in the left and right gaps of a meter bridge, the balance point is found at a distance l_(1) from the zero end of the meter bridge wire. An unknown resistance X is now connected in parallel to the resistance S and the balance point is found at a distance l_(2) from the zero end of the meter bridge wire, Obtain a formula for X in terms of l_(1), l_(2) and S.

    Which one of the following electrical meter has the smallest resistance ?

    STATEMENT-1 : In a meter bridge, if its wire is replaced by another wire having same length, same material but twice the cross sectional area, then the accuracy of measurement decreases. and STATEMENT-2 : Accuracy of meter bridge depends on the length of wire.
