Hi,

I need help on this question. This is actually my working. I am certain i got my AC wrong. I1.
I seldom do AC source.
DC I should be correct.
Could anybody help?



Question is Find the steady current IL(T)
The answer is -2 +0.707 cos (10t - 45degrees) Ampere
I believe the 0.707 is the RMS. But cant figure anything out.

Thanks.

is the 3 a current source ac?
first find out the frequency of voltage source comparing 10t=wt
and frequency = w/2pi
and then find the reactances.
post back if u need any further help.
