The Attempt at a Solution
Here are two questions. I'm stuck on question 1, and need someone to check question 2.
For the first question I see C2, C3, and C4 in parallel, so Ceq of those 3 are C2 + C3 + C4 = 3C
but now how do I continue? seems like the 3 remaining capacitors aren't in series or parallel..
Am I suppose to use Y-delta transformation?
For the 2nd question.
I see the top 3 inductors are in series and the botton 3 are in series.
Therefore L1 + L2 + L3 = 3L
at the bottom row, L4 + L5 + L6 = 3L
now we have 3L and 3L in parallel connection, 1/Leq = 1/3L + 1/3L
Leq = 3/2 L
