24 volts (although you'll ruin the 12v battery this way). If you're trying to get 36 volts, you want to wire them in series.
A single AA battery will produce 1.5 volts. In series the voltage is additive. In parallel the voltage remains the same but the batteries total capacity is increased.
1.55 volts
Depends on how you connect them together. Connected them in a series and you will have 18 volts. Connected them in parallel and you will still have 9 volts just double the capacity of 1 battery. Click the link to see these 2 connections.
A good AA battery has about 1.5 volts across it.
