Question

The current 'i' in an inductance coil varies with time 't' according to following graph

Which one of the following plots shows the variations of voltage in the coil

  1.    
  2.    
  3.    
  4.    

The correct answer is:


    (1) For time interval 0 < t < T/2
    I equals k t comma where k is the slope
    For inductor as we know, induced voltage V equals negative L fraction numerator d i over denominator d t end fraction
    rightwards double arrow V subscript 1 end subscript equals negative K L
    I equals negative K t rightwards double arrow V subscript 2 end subscript equals K L
