# Transfer function of RLC circuit

I'm trying to find the transfer function but I'm a little bit confused about how to solve this. I can't solve for the two Ls in parallel

How I can know what type of filter is this? I think it's a low pass filter, but I don't now if the 2 Ls can change it.

I'm trying to do this one too. Is it the same as the first one? I have to solve this as two parallel Ls in series to each other?

Thank you.

This is just an exercise in impedance. $$Z_R = R\\ Z_C = -j\frac{1}{\omega C} \\ Z_L = j\omega L$$ After that, you just think of everything as "generalized resistors", solving it as regular resistor networks.
