Basic Galvanometer

To determine which galvanometer has higher voltage sensitivity, we need to calculate the voltage sensitivity for both galvanometers and compare them. Given:
- Galvanometer :
- Resistance,
- Current sensitivity,
- Galvanometer :
- Resistance,
- Current sensitivity,

Step 1: Calculate Voltage Sensitivity Voltage sensitivity is given by: where is the current sensitivity and is the resistance of the galvanometer.

Step 2: Calculate Voltage Sensitivity for

Step 3: Calculate Voltage Sensitivity for

Step 4: Compare Voltage Sensitivities Clearly, .

Final Answer: This corresponds to option (4).
