Some limitations of a meter bridge include:

  1. Limited accuracy due to human error in taking measurements.
  2. Restricted use in measuring resistance values that are too high or too low.
  3. Sensitivity to external factors like temperature and vibrations, which can affect the readings.
  4. Inherent resistance in the connecting wires can introduce errors in the measurements.

In physics what is the use of meter bridge?

A meter bridge is used to measure an unknown electrical resistance by comparing it with a known resistance. It works on the principle of Wheatstone bridge. By balancing the bridge circuit, the value of the unknown resistance can be calculated accurately.


What is end correction in meter bridge?

End correction in a meter bridge refers to the added resistance due to the non-zero dimensions of the connecting wires or strips at the ends of the bridge. This added resistance needs to be accounted for when using the meter bridge for precise measurements. Calculating the end correction helps ensure accurate results when determining unknown resistances.


What is effect of interchanging the galvanometer and driver cell in meter bridge?

Interchanging the galvanometer and driver cell in a meter bridge would reverse the deflection of the galvanometer. The direction of current through the bridge wire would also change, affecting the balance point. The new balance point will now represent a different ratio of the unknown resistance to the known resistance.


Limitations of the wheatstone bridge?

The Wheatstone bridge can be sensitive to environmental factors like temperature changes and can be affected by resistance variations in the arms of the bridge. It requires precise resistor values for accurate measurements and can be limited in its ability to measure very small changes in resistance.


Why do you use a meter bridge for measurements rather than a voltmeter and ammeter?

A meter bridge is used in some cases for precise resistance measurements. It can be more accurate than using a voltmeter and ammeter because it eliminates errors from contact resistance and internal resistance of the instruments. This method allows for more accurate determination of resistance by comparing two resistance values directly.

What is the function of a Carey foster bridge?

A Carey-foster's bridge is a modified version of the meter bridge (wheatstone bridge or potentiometer). It can be used to find out the average resistance per unit length of the meter bridge wire and hence find out the unknown resistance. It is more accurate and more sensitive than a meter bridge.

What is the reason of the frequency limitation in bridge?

A bridge has an upper frequency limit because above that frequency the measuement accuracy fails because of stray capacitance and inductance inside the bridge device.


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.

How do you measure end correction of a meter bridge?

The end correction of a meter bridge can be measured by comparing the balance point of a known standard wire to the balance point of an unknown wire on the meter bridge. The difference in lengths between the two balance points is equal to the end correction.

What is the use of jockey in meter bridge?

In a meter bridge, the jockey is used to slide along the wire to make contact with the resistance wire and balance the bridge by finding the null point. This allows for accurate measurement of unknown resistance by comparing it with a known resistance.
