The magnetic flux through a circuit of resistance `R` changes by an amount `Deltaphi` in a time `Deltat`. Then the total quantity of electric charge `Q` that passes any point in the circuit during the time `Deltat` is represent by
A. `Q=(Deltaphi)/R`
B. `Q=(Delta phi)/(Deltat)`
C. `Q=R.(Deltaphi)/(Deltat)`
D. `Q=1/(R ) .(Deltaphi)/(Deltat)`
