Question

Which is a wrong statement

• A. The Wheatstone bridge is most sensitive when all the four resistances are of the same order
• B. In a balanced Wheatstone bridge, interchanging the positions of galvanometer and cell affects the balance of the bridge
• C. Kirchhoff's first law (for currents meeting at a junction in an electric circuit) expresses the conservation of charge
• D. The rheostat can be used as a potential divider

Answer 1

Answer: (B)

In a balanced Wheatstone bridge, interchanging the positions of galvanometer and cell affects the balance of the bridge

Answer 2

In balanced Wheatstone bridge, the arms of galvanometer and cell can be interchanged without affecting the balance of the bridge.
