In a meter bridge circuit as shown in the figure, the bridge is balanced when `AJ = 20` cm. On interchanging P and Q the balance length shifts by

The bridge show in figure will be balanced when:-

In wheat stone bridge P and Q are approximately equal. When Ris 500Omega the bridge is balanced. On interchanging P and Q, the values of R is 505Omega for balanching. The value of S is

A meter bridge setup is shown in the figure. If there is null deflection in galvanometer when length AC = 20 cm, then the value of resistance R is

A Wheatstone's bridge shown in figure, is to be balanced. The value of X must be

In a Wheatstone bridge the ratio arm P and Q are approximately equal. When R = 500Omega the bridge is balanced. On interchanging P and Q the value of R is 505Omega . Calculate the value of S.

A Wheatstone's bridge is shown in figure. The condition for balancing the bridge is

Resistance in the two gaps of a meter bridge are 10Omega and 30 Omega respectively . If the resistances are interchanged the balance point shifts by

The figure below shows a wheatstone bridge with resistors P and Q having almost equal resistance. When R = 400 Omega , the bridge is in balanced condition. If on interchanging P and Q, the bridge is again balanced for R = 405 Omega , then the value of X is

The figure below shows a wheatstone bridge with resistors P and Q having almost equal resistance. When R = 400 Omega , the bridge is in balanced condition. If on interchanging P and Q, the bridge is again balanced for R = 405 Omega , then the value of X is
