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.
When a Wheatstone bridge is in a balanced condition the center voltmeter in the bridge?
When the resistance in all four are equal
Why a wheatstone circuit is called a bridge?
An electrical circuit used to measure an unknown electrical resistance is called a Wheatstone bridge. It is called a bridge because it balances two legs of a bridge circuit.
Limitations of the wheatstone bridge?
The limitation of the wheatstone is that it may give inaccurate readings if not balanced.
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.

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 The galvanometer (which was used to measure voltage) has now been replaced by the Multimeter.Both are not used today.AnswerA Wheatstone Bridge has most definitely NOT been replaced by a multimeter!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.
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.
State 3 functions of wheatstone bridge?
Wheatstone bridge is used to calculate the resistance of unknown resistor in the circuit.
In a balanced condition of a bridge circuit a bulb was placed instead of galvanometer will the bulb light up?
No, It will go out.
Why using wheatstone bridge in transducer?
You use a transducer in a wheatstone bridge. The wheatstone bridge allows you to find an unknown resistance.
What is the difference between Wheatstone bridge and meter bridge?
WHEATSTONE BRIDGE : A wheatstone bridge is used to measure an unknown electrical resistance by balancing two legs of a bridge circuit, one leg of which includes the unknown compound.Its operation is similar to the original potentiometer. METER BRIDGE : A uniform resistance wire 1 meter in length, mounted above a scale marked in millimeters, with terminals added to make the device usable as either part of a wheatstone bridge or of a potentiometer.
