An inductor of 7.00 with negligible resistance is joined across an ac source whose voltage amplitude is kept constant at 67.2, however whose frequency can be varied.
i) Determine the current amplitude if the angular frequency is 100 rad/s.
ii) Determine the current amplitude if the angular frequency is 1000 rad/s.
iii) Determine the current amplitude if the angular frequency is 1.00*10^4 rad/s.
