An ideal inductor of inductance L is connected to an ac power supply, which provides an emf

Question:

An ideal inductor of inductance L is connected to an ac power supply, which provides an emf ℰ(t) = ℰm sin w t.
(a) Write an expression for the current in the inductor as a function of time.
(b) What is the ratio of the maximum emf to the maximum current? This ratio is called the reactance.
(c) Do the maximum emf and maximum current occur at the same time? If not, how much time separates them?
