The magnetic flux through a circuit of resistance `R` changes by an amount `Omegaphi` 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 byA. `Q=(1)/(r ).(Deltaphi)/(Deltat)`B. `Q=(Deltaphi)/(R )`C. `Q=(Deltaphi)/(Deltat)`D. `Q=(R ).(Deltaphi)/(Deltat)` |

Answer» Correct Answer - D The emf induced in the circuit `e=(Deltavarphi)/(Deltat)` If `R` is the resistance of the circuit, then `i=(e)/(R )=(Deltavarphi)/(Rdeltat)` thus, charge passes through the circuit, `Q=ixxDeltat` `impliesQ=(Deltavarphi)/(Rdeltat)xxDeltat` `impliesQ=(Deltavarphi)/(R )` |
