Confused....Imagine that

I have a simple series circuit that I built to show my students how amperage is read. I have two AA batteries, fully charged. I have a switch and a fixture with a small bulb. I read approx. 3 volts at the battery box. I read approx. 1.5 ohms resistance from bulb/fixture. Should read approx 2 amps of current. Reading .23 amps with Fluke multimeter set to autorange. Can't figure out why.

a AA battery cant output 2A. Try a larger resistance, Also a light bulb changes resistance with temperature
