The magnetic flux through a circuit of resistance R changes by an amount in a time t. Then the total quantity of electric charge Q that passes any point in the circuit during the time t is represented by

  1. Q = 1R t
  2. Q = R
  3. Q = t
  4. Q = R t

Answer

(2) Q = R

Solution

Induced emf: = t

Induced current: I = R = R t

Q = I t = R (independent of the time taken)

Answer: (2)
