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=-(Delta phi)/(Delta t)+R`
B. `Q=(Delta phi)/(R)`
C. `Q=(Delta phi)/(Delta t)xxR`
D. `Q=(Delta phi)/(Delta t)`

Answer

B

Explanation

BY Faraday's law, `e=(Delta phi)/(Delta t) :. i = e/R = (Delta phi)/(Rdeltat)`
`:. i(Delta t) = (Delta phi)/R :. Delta Q = (Delta phi)/R or Q = (Delta phi)/(R)`.
