The Attempt at a Solution
My only real thought of how I could solve this would be either to do a nodal analysis of the essential node connecting the three branches with elements, OR, I could source transform my voltage function generator into a current function and use that to do a mesh current analysis.
I'm not 100% sure if nodal analysis works in this case because of the branch containing the 150H Inductor and the 100 Ohm resistor. It seems like nodal analysis usually only contains one element per branch (or in my past experience, I was able to combine multiple resistors in series within a single branch).
If I do a mesh current analysis, using I=V/R, I can convert my source into 4/5cos(377t) current function in parallel with my 150 ohm resistor. However, with this method, I'm pretty unsure of myself. This is my circuit after a source transformation:
I don't think I'm able to do a mesh current analysis here because of the fact there is only one source.
I am also not supposed to convert this to a phasor (yet). That's a later part of the this problem, which I think I figured out on my own. It's just this particular part of the problem, all the RLC circuit's we've dealt with have either been completely parallel, or completely series. Never a mixture like this one. The resistor in series with the inductor is particularly puzzling to me, as I'm not sure how to handle it.
Any help?
