Question

A choke coil is preferred to a rheostat in ac circuit as

  1. It consumes almost zero power    
  2. It increases current    
  3. It increases power    
  4. It increases voltage    

The correct answer is: It consumes almost zero power


    A choke coil contains high inductance but negligible resistance, due to which power loss becomes appreciably small.

    The figure shows four wire loops, with edge lengths of either L or 2L. All four loops will move through a region of uniform magnetic field stack B with rightwards arrow on top (directed out of the page) at the same constant velocity. Rank the four loops according to the maximum magnitude of the e.m.f. induced as they move through the field, greatest first
