Question

A galvanometer has spring constant k, magnetic field B, and deflection angle theta. The coil has N turns and area A. Which is the condition for equilibrium when current I flows?
Options
A kB = theta*I*A*N
B k*theta = B*I*A*N
Correct Answer
C BI = k*theta*A*N
D k*theta = BA/(IN)
Correct Answer

Option B is the correct answer.

Detailed Explanation

Spring torque balances magnetic torque: k*theta=NBIA.

Hint

Spring torque balances magnetic torque: k*theta=NBIA.
