In Wheatstone bridge experiment a student by mistake, connects key (K) in place of galvanometer and galvanometer (G) in place of key(K). How will be the test for the balance of the bridge?

What happens if the galvanometer and cell are interchanged at the balance point of the bridge? Would the galvanometer show current?

In a metre bridge, the balance point is found to be at 39.5 cm from the end A, when the resistor Y is of 12.5 Omega . Determine the resistance of X. Made of thick copper strips? Determine the balance point of the bridge above if X and Y are interchanged. What happens if the galvanometer and cell are interchanged at the balance point of the bridge ? Would the galvanometer show any current?

The given Wheatstone Bridge shows no deflection in the galvanometer joined between the points B and D.Calculate the value of ‘X’.

The resistance of each arm of the wheat stone bridge is 10Omega . A resistance of 10Omega is connected in series with galvanometer then the equivalent resistance across the battery will be

The given Wheatstone Bridge shows no deflection in the galvanometer joined between the points B and D. Calculate the value of ‘X’.

A coil of 500 turns and area 0.04 m^2 is placed in a region of transverse magnetic field of field of 0.25 Wb m^-2 . The coil is roated through 90^@ about its diameter with a particular angular velocity in 0.2 s. The coil is connected to a galvanometer in series having a resistance of 25 ohm. Calculate the total change flow through the galvanometer.

Draw the circuit diagram of Wheatstone bridge. Under what condtion, no current flows through its galvanometer (balanced condition)?
