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.
End correction in a pipe refers to the adjustment made to account for the influence of the end effects on fluid flow. These effects occur due to the changes in fluid behavior near the open ends of the pipe, such as velocity profiles and pressure distribution. A proper end correction ensures more accurate measurements in pipe flow systems.
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.
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.
Some limitations of a meter bridge include: Limited accuracy due to human error in taking measurements. Restricted use in measuring resistance values that are too high or too low. Sensitivity to external factors like temperature and vibrations, which can affect the readings. Inherent resistance in the connecting wires can introduce errors in the measurements.
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.
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.
The job of the server in a data acquisition setup is to bridge the gap from the meter to dashboard. These servers help to make a complete end-to-end solution.
The significance of end correction is that it is used in the radiation acoustic impedance of a circular piston.
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.
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.

End correction occurs in measurements due to the physical dimensions of the measuring instrument or device. The end correction accounts for the fact that the measuring point is located at some distance from the end of the instrument, requiring an adjustment to ensure accurate measurements. This correction is necessary in various fields, such as acoustics, fluid mechanics, and metrology, to ensure precision in calculations and results.

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.
