Answer to Question #150595 in Mechanical Engineering for MD SHAHID

Question

The inductance of moving iron ammeter in micro henry is given by expression:

L=20+5θ-2θ2

Where θ is deflection in radians from the zero position. Determine the angular in radians for a current of 10A if the for a current of 5A is 300.Also determine the spring constant.

Answer 1

KC = 69.502

$\theta = 84.50^0$
