2. It can be shown that the voltage from the AC source is described by V = Vmax Cos (wt + $) where o is the phase angle found as part of your work in part (a). The voltage across individual circuit elements is the same as described in Lecture 14. Consider all this, what is the energy stored in the inductor at the instant that the instantaneous source voltage is zero for the first time? Hint: make sure to convert your phase angle to radians when solving for time if you are using angular frequency.
