Actually this is not exactly a homework. I am trying to understand the following situation only.
Consider a ring shaped coil of N turns and area A. Connect it to an external circuit with a twisted pair of leads ( this info is trivial). The resistance of the circuit along with the coil itself is R. Now the coil in a magnetic field.
Suppose the flux through the coil is somehow altered from its initial steady state value (A) to final value (B).
The author claims that the total charge Q that flows through the circuit as a result is independent of the rate of change of the flux. I am having hard time understanding this. Can anyone help me understand it.

The Attempt at a Solution
faraday's law is the most relevant law here, according to the book. But I am just not getting what the author is saying.
