when an AC passes through a capacitor,if the expression for alternating voltage is V=E×Sinωτ,the expression for current is (I×sin(ωτ+∏/2)).This shows that current leads voltage by a phase ∏/2.Also at τ=0,we have voltage=0 but there is a finite value of current.In absence of voltage at T=0,where from this current comes? please give detailed explanation & please don't consider it to be a home-work question.
