Question

In a tangent galvanometer, a current of 1A is required to produce a deflection of 60° is:

• A. 3A
• B. 2A
• C. 1A
• D. 4A

Hint:

The current required to produce a deflection in a tangent galvanometer depends on the coil's properties and the deflection angle.

Answer 1

The Correct Option is A

Step 1: Use the tangent galvanometer formula.
The formula for the current in a tangent galvanometer is: \[ I = \frac{B}{r} \cdot \tan(\theta) \] Where: - \( B \) is the magnetic field, - \( r \) is the radius of the coil, - \( \theta \) is the deflection angle.
Step 2: Conclusion.
By applying the given conditions, we calculate the value of \( I \) to be 3A.
