The magnetic flux through a coil of resistance R changes by an amount in the time t . The total quantity of electric charge ( Q ) induced is

Options

  1. AQ = - t + R
  2. BQ = t R
  3. CQ = R
  4. DQ = t

Correct answer

C. Q = R

Step-by-step solution

According to Faraday's law of electromagnetic induction, the magnitude of induced emf is given by |e| = t The induced current in the coil of resistance R is I = |e| R = R t The total quantity of electric charge Q induced in time t is Q = I t = ( R t ) t = R Answer: Q = R
