State Wheatstone bridge principle. Use kirchoff'slaws to obtain the relation bteween the resistance in four arms of the Wheatstone bridge by drawing circuit diagram.

Using Kirchoff's law, derive the condition for the balance of a Wheatstone bridge circuit.

Deduce the conditions for balance in a wheatstone bridge. Using the principle of Wheatstone bridge, describe the method to determine the specific resistane of a wire in the laboratory. Draw the circuit diagram and write the formula used. Write any two important precautions you would observe, while performing the experiment.

Discuss a practical form of a Wheatstone's Bridge to find an unknown resistance.

How does the term ohmic resistance differ from impedance? With the help of a suitable phasor diagram, obtain the relation between impedance and resistance in an a.c. series LCR circuit.

[Tick the correct option]Wheatstone bridges is most sensitive, when resistances in four ration arms are of
