The current (I) in the inductance is varying with time according to the plot shown in a figure.

Solution

D.

For inductor as we know induced voltage
For t= 0 to t= T/2
straight V space equals straight L dI over dt space equals space straight L straight d over dt open parentheses fraction numerator 2 straight I subscript straight o straight t over denominator straight T end fraction close parentheses space equals space constant comma
space for space space straight t equals space straight T divided by 2 space to space straight t equals space straight T
straight V space equals LdI over dt open parentheses fraction numerator negative 2 straight I subscript straight o straight t over denominator straight T end fraction close parentheses space equals space minus space constant
therefore comma space answer space will space represent space by space graph space left parenthesis straight d.
