You need to calculate the amperage of all the things you want to use. From
your description, it certainly sounds like one 20 amp circuit is going to do
it

Ok need to run electrical wiring underground to 2 outbuildings located on
different sides of my lot.

Building A
Needs 4 wall outlets, 2 light fixtures and a light switch. Everything
should be 110V in this building
Just mainly need power for lights but may use other devices once in a
while.

Building B
Needs 5 wall outlets, 2 light fixtures and a light switch. Needs 1 outlet
220V for air compressor.
Needs the 220 for a air compressor, will run power tools (skill saw, misc
drills etc....)

Now the way I understand it sounds like I can run a single wire into a
junction box inside building B. Is that the case? What size wire will I
need for this? For both buildings will I need to place the wire in
conduit all the way from the house into the building underground? If so
what kind of conduit? Do I need each building on seprate breakers? What
breaker(s) size do I need? Do I need 12-2 wire or 14-2 for each of the
buildings?

I think I am looking for the outdoor wire located
