What is end error in meter bridge? How can remove it

Posted by Ganesh Verma 6 years, 1 month ago

CBSE > Class 12 > Physics

Prabhkirat Brar 6 years, 1 month ago

End error: The shifting of zero of the scale at different points as well as the stray resistance due to non-uniformity of metal wire gives rise to end error in meter bridge. How to overcome end error? End error can be removed by repeating the experiment by interchanging unknown and known resistance and finally taking the mean value of resistance obtained in each experiment.Read more on Sarthaks.com - https://www.sarthaks.com/544799/what-error-meter-bridge-how-overcome-the-resistance-arms-the-meter-bridge-and-respectively
