At what condition the voltmeter connected across the wheatstone bridge will be zero?
At a balanced condition the voltmeter connected across the wheatstone bridge will be zero.
Could a voltmeter be used in a wheatstone bridge instead of an ammeter?
Yes, of course.
Why doesn't any current flow through the galvanometer in a balanced Wheatstone bridge?
There is no current flow through the galvanometer in a balanced Wheatstone bridge because, in the balanced state, the voltage on both terminals of the galvanometer is the same. Since the voltage differential in zero, there can be no current.
Why using wheatstone bridge in transducer?
You use a transducer in a wheatstone bridge. The wheatstone bridge allows you to find an unknown resistance.
How do you obtain a null reading on wheatstone bridge?
obtaining condition p/q=r/s
At what condition the voltmeter connected across the wheatstone bridge will be zero?
At a balanced condition the voltmeter connected across the wheatstone bridge will be zero.
Limitations of the wheatstone bridge?
The limitation of the wheatstone is that it may give inaccurate readings if not balanced.

Why galvanometer is connected in wheatstone bridge?
A Wheatstone Bridge is used to measure resistance of an electrical / electronic component. The galvanometer (which was used to measure voltage) has now been replaced by the Multimeter.Both are not used today.AnswerA Wheatstone Bridge has most definitely NOT been replaced by a multimeter! It uses a completely-different method of measuring resistance and is significantly more accurate than a multimeter. The purpose of the very sensitive galvanometer is to detect when the Bridge circuit is 'balanced', by sensing the current (not voltage!) passing through it. When no current flows, the Bridge is balanced.
How do you obtain a null reading on wheatstone bridge?
obtaining condition p/q=r/s

How does the Kelvin bridge differ from the wheatstone bridge?
kelvin's bridge is the modified version of wheatstone bridge and used to measure resistance values less than 1 ohm.
What is Wheatstone's bridge?
The wheatstone bridge is an instrument used to measure electrical resistance by means of balancing a bridge circuit. The bridge circuit contains two legs, one of which contains the unknown resistance. Variations in wheatstone bridge can be employed to measure inductance, capacitance, and impedance also.
