I am trying to do some DIY capacity testing of my NiMH batteries. However when I connect, for example, a fully charged D cell in series with a 1 Ohm 5W power resistor I measure a current of 0.31A. With a 0.33Ω I get 0.38A and with 0.22Ω I get 0.41A.
According to Ohm's law I was expecting a current of 1.2A with the 1Ω given a 1.2V battery. Am I mistaken and I there any way I can draw currents of above 1A using resistors?
Thanks in advance.
