Gday, first post :)

No ones asking me to figure this out but im trying to figure it myself. Simply have a few resistors in parallel on this breadboard powered by either a battery or Arduino and they always give me the same current values across each resistor.

Why aren't I getting differing values as the theory tells me for parallel resistance?

Thanks.Resistors-Para.jpg

Your theory is a little off. ;)
You don't measure current "across" a resistor, you measure voltage.
Current is measured through a resistor.
This means you hook an ammeter in series with each resistor to find its current.
