Well, technically it would be 6A. AA batteries are 1.5V *4/1Ohm. But, most AA batteries can't push that much current even brand new. Usually the voltage will drop until it's at a level that they can push. The current is produced from a chemical reaction inside the batteries that usually just can't sustain that amperage. You'd be lucky to get that for even ten minutes. Many batteries have trouble even pushing 1 amp.
Assuming they AA are the common 1.5 volt type and in series, 4 batteries times 1.5 volts = 6 volts. Ohms law to figure out amperage is voltage divided by resistance equals amperage. So 6 volts divided by 1 ohm = 6 amps.

As these are 1.5V batteries we now know that the total voltage is 6V, assuming that the batteries are in series with each other.
Now all we need to do is to use Ohms law...
V=I x R
which transposes to
I = V / R
so
I = 6 / 1
I = 6A
for an encore:
W = I x V
W = 6A x 6V
W = 36 Watts
