The magnetic flux through a circuit of resistance R changes by an amount d\(\text { Ф }\) in a time dt. The quantity of electric charge Q that passes through any point in the circuit during the time dt is represented by
  1. \(\frac{d Q}{d t}=\frac{1}{R} \frac{d Q}{d t}\)
  2. \(\frac{d Q}{d t}=\frac{d \Phi}{d t}\)
  3. \(\frac{d Q}{d t}=R \frac{d Q}{d t}\)
  4. \(\frac{d Q}{d t}=R^{2} \frac{d Q}{d t}\)

Answer

(A) d Q d t = 1 R d Q d t
