A voltage waveform V (t) = 12 t 2 is applied across 1 H

A voltage waveform V (t) = 12 t ² is applied across 1 H inductor for t 0, with initial current through it being zero the current through the inductor for t 0 is given by—

Current across inductor is given by the relation.

i =	1		^t	V dt
	L		₀

=	1		^t	12t ² dt
	1		₀

= 12	t³	= t³
