Question

An e.m.f. of 12 blank v o l t s is induced in a given coil when the current in it changes at the rate of 48 blank a m p e r e s blank p e r blank m i n u t e. The self inductance of the coil is

  1. 0.25 blank h e n r y  
  2. 15 blank h e n r y  
  3. 1.5 blank h e n r y  
  4. 9.6 blank h e n r y  

The correct answer is: 15 blank h e n r y


    L equals fraction numerator e over denominator d i divided by d t end fraction equals fraction numerator 12 over denominator 48 divided by 60 end fraction equals 15 blank H

    A highly conducting ring of radius R is perpendicular to and concentric with the axis of a long solenoid as shown in fig. The ring has a narrow gap of width d in its circumference. The solenoid has cross sectional area A and a uniform internal field of magnitude B subscript 0 end subscript. Now beginning at t equals 0, the solenoid current is steadily increased so that the field magnitude at any time t is given by B open parentheses t close parentheses equals B subscript 0 end subscript plus alpha t where a greater than 0. Assuming that no charge can flow across the gap, the end of ring which has excess of positive charge and the magnitude of induced e.m.f. in the ring are respectively
