The magnetic flux through a circuit of resistance R changes by an amount \(\Delta \phi\) in a time \(\Delta t\). Then, the total quantity of electric charge Q that passes through any point in the circuit during the time \(\Delta t\) is represented by:
- \(Q=\frac{1}{R} \cdot \frac{\Delta Q}{\Delta t}\)
- \(\mathrm{Q}=\frac{\Delta \mathrm{q}}{\mathrm{R}}\)
- \(\mathrm{Q}=\frac{\Delta \mathrm{q}}{\Delta \mathrm{t}}\)
- \(\mathrm{Q}=\mathrm{R} \cdot \frac{\Delta \mathrm{q}}{\Delta \mathrm{t}}\)
Answer
(B) Q = q R
