Question

In a meter bridge for measurement of resistance, the known and unknown resistance are intercharged and mean reading is calculated for null point measurement. The error hence removed is

• A. End Correction
• B. Index error
• C. Temperature effect
• D. Random error

Answer 1

The correct option is A End Correction

In a meter bridge experiment, it is assumed that the resistance of the $\text{L}$ shaped plate is negligible, but actually it is not so. The error created due to this is called end error. To remove this, the resistance box and the unknown resistance must be interchanged and then the mean reading must be taken.

Hence, option $\left(a\right)$ is the correct answer
