The Voltage V Across a 4 H Pure Inductor Varies

The voltage v across a 4 H pure inductor varies with time t according to the equation v = 18 sin (2π x
1000t - 30º) V. The current through the capacitor will thus be:

A) i = 18 sin (2π x 1000t - 30º) mA
B) i = 18 sin (2π x 1000t - 120º) mA
C) i = 0.72 sin (2π x 1000t - 30º) mA
D) i = 0.72 sin (2π x 1000t - 120º) mA
