A 25 A electrodynamic ammeter is controlled by a spring having a constant of 5.7295x 10 Nm/rad. The full scale deflection is 110°. Determine the inductance of the instrument while measuring a current of 20 A. The mutual inductance at 0° deflection is 4 u H and the change in mutual inductance is linear with the deflection.
