1.The current of a battery is decided by the resistance of electronics used.(Correct me if I am wrong).So there is no limit to current than can be taken from a battery (Except the time)
2.Is this also true for AC(No limit for current that can be taken out) If both of the statements are true, then why there is ampere listed in the dc adapter (mobile adapter).
3.When I use the DC adapters for my project what should I take into consideration (Should I take the amperage listed into consideration)

The current rating of the adaptor is the maximum current it is designed to supply. Try to take more current and it will go low volts/fuse/catch fire/end up as a molten mess. So always chose an adaptor with greater current rating than your circuit needs. If it is a pulse circuit you can filter the current to produce a lower steady value.
