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

Options

A. `Q=(Deltaphi)/R`
B. `Q=(Deltaphi)/(Deltat)`
C. `Q=R.(Deltaphi)/(Deltat) `
D. `Q=1/R. (Deltaphi)/(Delta t)`

Answer

A

Explanation

`I=e/R=I/R((Deltaphi)/(Deltat))=(DeltaQ)/(Deltat) rArr Q = (Deltaphi)/R`
