I measured current through a parrallel circuit and my multimeter fluctuated massively and compared to theoretical values they are miles out. multimeter was changed over to ampmeter. I used duel power supply. Throughtout the measuring i kept getting short circuits. The circuit on the breadboard was compact and resistors kept touching and leads kept touching other resistors.

would this of accounted for the massive difference between theory values and practical as well as the fluctuation on the scale?
What are possible causes of low current and fluctuation?

With such a vague description of what you are doing, it's hard to say. How about an exact circuit diagram with descriptions of the components.

I see no indication of where the meter was hooked up and no indication of where shorts occurred.

Also, you originally said a parallel circuit but I see no parallel circuit here.

connected to the 33omh resistor and shot occurred between the 33 and 15 path.
sorry meant single
