In meter bridge or wheatstone bridge for measurement of resistance, the known and the unknown resistances are interchanged.

Question 1

In meter bridge or wheatstone bridge for measurement of resistance, the known and the unknown resistances are interchanged. The error so removed is

(a) End correction

(b) Index error

(c) Due to temperature effect

(d) Random error

Question 2

Correct option(a)

Explanation:

Sometimes at the end points of meter bridge wire, some length is found under the metallic strips, so some additional length should be added for accurate measurement, if the end resistance is small, if can be achieve by interchanging the resistances.
