So, I have a circuit:

___ 
D1 \,/ S
===== S
 S
VR + S 2 mH inductor
 S
===== S
D1 /^\ S
 S
 
++




D1 and D2 are Varactors. I'm supposed to find the value of D1 and D2
for a resonance of 1MHz.
I went with 1MHz = 1/(2Ï€*2mH*C) which results in C=50.6pF
So, I'm not entirely sure if that is the entire capacitance of the
circuit, or the capacitance of of each of D1 and D2.
This homework exercise is about varactors, but I have skipped the
"Introduction to AC" class, so my basic understanding of the above
circuit as an LC circuit is lacking. If I understood that much of it, I
know I'd understand the varactor part.
Any hints, help, suggestions would be appreciated.
Thanks,
Daniel.
