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.

∙ 14y agoA Wheatstone bridge can be used to measure resistances on all kinds of electronic equipment, or pinpointing short circuits, but they can be especially useful in measuring very low resistances such as shorted primary windings in Transformers or coils. or measuring any resistance to small to be accurately be measured by a conventional ohm meter.

∙ 13y agoA network of resistors which can be used to (for example) measure resistance. Electric current is divided into two resistor arms, A and B and rejoined at the other end to continue the flow. A connection point X is made along the arm A, and another point Y on arm B. A voltmeter is connected between X and Y. This kind of circuit is called a Bridge (invented by Prof Wheatstone of London, England). When the meter indicates zero current between X and Y it implies that the potential (voltage) at X is the same as at Y, which means the ratio of the resistances AX to XB is the same as the ratio of resistances AY to YB, independent of the voltage supply. This circuit can be used to measure currents and voltages also.

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.
Why using wheatstone bridge in transducer?
You use a transducer in a wheatstone bridge. The wheatstone bridge allows you to find an unknown resistance.
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.
State 3 functions of wheatstone bridge?
Wheatstone bridge is used to calculate the resistance of unknown resistor in the circuit.
Could a voltmeter be used in a wheatstone bridge instead of an ammeter?
Yes, of course.

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.
Could a voltmeter be used in a wheatstone bridge instead of an ammeter?
Yes, of course.
What are the two main types of bridges in electricity?
The two main types of bridges in electricity are Wheatstone bridge and Kelvin bridge. The Wheatstone bridge is used to measure resistance while the Kelvin bridge is used to measure low resistance values. Both bridges are commonly used in electrical and electronic circuit analysis for accurate measurements and fault detection.
