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.

Why is it important to place a potentiometer in the wheatstone bridge ohmmeter circuit?

A potentiometer is essential in a Wheatstone bridge ohmmeter circuit because it allows for precise adjustment of resistance, enabling accurate balancing of the bridge. This fine-tuning helps eliminate errors due to variations in the bridge's arms or external factors. By ensuring that the bridge is balanced, the potentiometer enhances measurement accuracy, allowing for reliable determination of unknown resistances. Overall, it plays a crucial role in achieving high precision in resistance measurements.

What is the difference between the Carey foster bridge and meter bridge?

There is no great difference between between the two in principlebut,In a Carey foster's bridge there is no end resistance whereas in the case of a metre bridge end resistance afffects our readings.Hence Carey foster bridge is more accurate than metre bridge .Carey foster bridge can also measure low resistance and high resistance but a metre bridge cannot do so.
