Discuss the working Principle of Wheat stone bridge. Explain with diagram how will determine the resistance of a resistor which is unknown using this method.

How resistance can be determined using the principle of Wheatstone bridge ? Derive the principle .

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

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

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

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 .

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

When the value of r in the balanced Wheatstone bridge, shown in the figure: is increased from 5 Omega to 7 Omega the value of S has to be increased by 3 Omega in order to maintain the balance. What is the initial value of S ?

A balanced Wheatstone bridge has resistances 100Omega , 10Omega, 500Omega and 50 Omega repectively in its four arms. Determine the ratio of powers consumed in its different arms.
