The magnetic flux through a coil of resistance $R$ changes by an amount $\Delta \phi$ in time $\Delta t$. The amount of induced current and induced charge in the coil are respectively:

• A
  $\left(\frac{\Delta \phi}{\Delta t}\right) R$ and $\frac{R}{\Delta \phi}$
• B
  $\frac{\Delta \phi}{R}$ and $R\left(\frac{\Delta t}{\Delta \phi}\right)$
• C
  $\frac{\Delta \phi}{R}+R$ and $\frac{\Delta \phi}{\Delta t}$
• D
  $\left(\frac{\Delta \phi}{\Delta t}\right) \times \frac{1}{R}$ and $\frac{\Delta \phi}{R}$
