There is a simple a.c generator it consists of a coil of wire rotating between the poles of a permanent magnet! The output is fed to an external circuit through brushes making contact with two slip rings. state two factors on which the size of the output curretn depends!

a) The output voltage of the generator
b) The resistance of the external circuit
c) (extra credit?!)--- The internal resistance of the generator.

I like the other Steve's answer. I will assume you refer to the power output the generator can produce. My answer is:
1. the strength of the magnetic field.
2. the number of turns in the coil.

i love a number of consumer-pleasant Plan. i love one music that I heard from Linkin Park. i love a pair songs with the help of Paramore. i love that one music I heard with the help of Hawk Nelson. i love one music I heard with the help of forestall. With PATD, I heard some their songs yet i do not keep in mind what they were. They were o.k.. it rather is those i love. :)
