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

Options

  1. At
  2. B- t +R
  3. CR
  4. Dt R

Correct answer

D. t R

Step-by-step solution

From Faraday's law of EMI, emf induced in the circuit is given by, e=- t And if R is the resistance in the circuit then it becomes, aligned & I= e R & I=- t R aligned So, the total amount of charge passing through the circuit will become, aligned & Q=I t & Q=- t R t & Q=- R aligned So, the total amount of charge passing through the circuit is given by R
