Question

How does the meter bridge overcome end error?

Answer 1

Explanation:

1. A Wheatstone bridge is a type of electrical circuit used to measure an unknown electrical resistance by balancing its two legs, one of which contains an unidentified component.
2. End error in a meter bridge is an error brought on by the scale's zero changing at various positions as a result of the non-uniformity of the metal wire.
3. The shifting of the scale's zero at various locations is referred to as end error. Additionally, the end error in the meter bridge is brought on by stray resistance in the metal wire as a result of non-uniformity.
4. Repeating the experiment while alternating between known and unknown resistance and taking the mean resistance value acquired in each trial will eliminate the final mistake.
