Differentiating the v(t) function yields the following: dv(t) = Vω cos ωt dt. or. I = CV(2πf) cos (2πf)t. However, since we are only looking at the current required to meet the peak voltage we must evaluate this equation at the point where the value is at its peak. The voltage is at its peak when cos ωt = 1.
