Which is a wrong statement [MP PMT 1994]

Kirchhoff's first law (for currents meeting at a junction in an electric circuit) expresses the conservation of charge

The Wheatstone bridge is most sensitive when all the four resistances are of the same order

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

The rheostat can be used as a potential divider
