Question

An e.m.f. of 12 blank v o l t is produced in a coil when the current in it changes at the rate of 45 blank a m p divided by m i n u t e. The inductance of the coil is

  1. 0.25 blank h e n r y  
  2. 1.5 blank h e n r y  
  3. 9.6 blank h e n r y  
  4. 16.0 blank h e n r y  

The correct answer is: 16.0 blank h e n r y


    d equals L fraction numerator d i over denominator d t end fraction rightwards double arrow 12 equals L cross times fraction numerator 45 over denominator 60 end fraction rightwards double arrow L equals 16 H

    There are two solenoids of same length and inductance L but their diameters differ to the extent that one can just fit into the other. They are connected in three different ways in series. (1) They are connected in series but separated by large distance, (2) they are connected in series with one inside the other and senses of the turns coinciding, (3) both are connected in series with one inside the other with senses of the turns opposite as depicted in figures 1, 2 and 3 respectively. The total inductance of the solenoids in each of the case 1, 2 and 3 are respectively
