Question

determine of ballistic constant of a moving coil galvanometer​

Answer 1

Answer:

Theory of Ballistic Galvanometer :

The angular momentum of the coil is equal to the force acting on the coil. Thus from equation (4) and (5), we get. The Kinetic Energy (K) deflects the coil through an angle θ, and this deflection is restored through the spring. The K is the constant of the ballistic galvanometer.
