Question:

In order to pass 10\% of the main current in a galvanometer of resistance \( R \), the required resistance of shunt should be:

Show Hint

Shunt resistance allows a controlled fraction of current to bypass the galvanometer.

The Correct Option is D

Solution and Explanation

Step 1: The shunt resistance is calculated as: \[ S = \frac{I_G R}{I - I_G} \] Step 2: Given 10\% current passes through the galvanometer, the correct answer is: \[ \boxed{R/11} \]
