The magnetic flux through a circuit of resistance R changes by an amount \[\Delta \,\phi \]in a time\[\Delta \,t\]. Then, the total quantity of electric charge Q that passes any point in the circuit during the time At is:

A) \[Q=\frac{\Delta \phi }{R\Delta t}\]                     

B) \[Q=\frac{\Delta \phi }{R}\]

C) \[Q=\frac{\Delta \phi }{\Delta t}\]                       

D) \[Q=\frac{R\Delta \phi }{\Delta t}\]
