If galvanometer and battery are interchanged in balanced wheat stone bridge then
(A) The battery discharges
(B) The bridge still balances
(C) The balance point is changed
(D) The galvanometer is damaged due to flow of high current

In a wheatstone bridge if the battery and galvanometer are interchanged then the deflection in galvanometer will

The Wheatstone's bridge shown in the Fig. A2.5 is balanced. If the positions of the cell C and the galvanometer F are now interchanged, G will show zero deflection

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

In the circuit in fig. If no current flows through the galvanometer when the key k is closed, the bridge is balanced. The balancing condition for bridge is

(i) 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? (ii). Determine the balance point of the bridge above if X and Y are interchanged. (iii). what happens if the galvanometer and cell are interchanged at the balance point of the bridge ? Would the galvanometer show any current?

Assertion: When wheatstone bridge is balanced then current through cell depends on resistance of galvanometer. Reason: At balancec condition current through galvanometer is very high.

Four resistors A, and D form a Wheatstone bridge. The bridge is balanced , when C = 100Omega If A and B are interchanged the bridge balances for C=121Omega . The value of D is

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

What is the change in experiment if battery is connected between B and D and galvanometer is connected across A and C ?

Answer the following : (a) Why are the connections between the resistors in a meter bridge made of thick copper strips? (b) Why is it generally preferred to obtain the balance point in the middle of the meter bridge wire?
