To find the resistance of the galvanometer, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Problem**: We know that the deflection in the galvanometer falls from 50 divisions to 10 divisions when a shunt of 12 ohms is applied. This indicates a change in the current through the galvanometer. 2. **Determine the Ratio of Currents**: The ratio of the current through the galvanometer (IG) after the shunt is applied to the current before the shunt is applied can be expressed as: \[ ...
