Establish the balanced condition of Wheatstone's bridge by applying Krichhoff's laws.

Establish the balanced condition of Wheatstone's bridge by applying Kirchhoff's laws .

Obtain the balanced conditon of Wheatstone bridge from Kirchhoff’s Law.

Write the Wheatstone bridge principle.

Statement I : If the resistance of the first two arms P and Q of a balanced Wheatstone bridge are exchanged , the balanced condition is not disturbed . Statement II : The balanced condition of a Wheatstone bridge is independent of the resistance of the galvanometer used .

Statement I : A balance is obatained at the position of 40 cm othe metere wire ,when 2Omega and 3 Omega resistances are put in the lift and right gaps respectively of a meter bridge Statement II : The balanced condition of a Wheatstone bridge is P//Q=R//S .

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

A coil of wire is kept in melting ice . Its resistance measured by a Wheatstone bridge is 5Omega . If the coil is heated to 100^(@)C and another wire of resistance 100Omega is coonnected in parallel to it , the balanced condition of the brige remains unchaged . Determine the temperature coefficient of resistance of the wire of the coil .
