List of top Physics Questions on Meter Bridge

A meter bridge with two resistances \( R_1 \) and \( R_2 \) as shown in figure was balanced (null point) at 40 cm from the point \( P \). The null point changed to 50 cm from the point \( P \), when a \( 16\,\Omega \) resistance is connected in parallel to \( R_2 \). The values of resistances \( R_1 \) and \( R_2 \) are 

In case of meter bridge experiment balance length for $2\Omega$ and $3\Omega$ is $\ell$ and for $x\Omega$ and $3\Omega$ is $(\ell + 10)$ cm. Find $x$.
In a metre-bridge, when a resistance of $2 \, \Omega$ is in the left gap and the unknown resistance in the right gap, the balance length is found to be 40 cm. On shunting the unknown resistance with $2 \, \Omega$, the balance length changes by:
The resistance per centimeter of a meter bridge wire is \( r \), with \( X \, \Omega \) resistance in the left gap. Balancing length from the left end is at 40 cm with 25 \( \Omega \) resistance in the right gap. Now the wire is replaced by another wire of \( 2r \) resistance per centimeter. The new balancing length for the same settings will be at:
Two resistances are connected in the two gaps of a meter bridge. The balancing point is obtained at 20 cm. When a resistance of \( 15 \, \Omega \) is connected in series with the smaller resistance of the two, the balancing point shifts to 40 cm. The value of smaller resistance is

In the given figure of meter of bridge experiment, the balancing length AC corresponding to null deflection of the galvanometer is 40 cm. The balancing length, if the radius of the wire AB is doubled, will be _______ cm.
