Question

A galvanometer with a scale divided into 100 equal divisions has a current sensitivity of 10 divisions per milliampere and a voltage sensitivity of 2 divisions per millivolt. The galvanometer resistance will be

• A. 4 \(\Omega\)
• B. 5 \(\Omega\)
• C. 3 \(\Omega\)
• D. 7 \(\Omega\)

Hint:

The resistance of a galvanometer can be calculated using its voltage and current sensitivity.

Answer 1

The Correct Option is B

The resistance of the galvanometer can be found by using the relation \( R = \frac{V}{I} \). The voltage sensitivity and current sensitivity provide the necessary values for calculating the resistance of the galvanometer.
