Question

The return spring of a galvanometer has spring constant 0.5 N/m. If the coil has area 2.25x10-4 m2, 75 turns, and magnetic field strength 0.4 T, calculate the sensitivity of the galvanometer.
Options
A 0.527 rad/A
B 0.216 rad/A
C 0.0552 rad/A
D 0.0135 rad/A
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

Sensitivity=NBA/k=(75)(0.4)(2.25e-4)/0.5=0.0135 rad/A.

Hint

Sensitivity=NBA/k=(75)(0.4)(2.25e-4)/0.5=0.0135 rad/A.
