Homework Statement
When I connect just the multimeter (as shown in the diagram) to the power source by inserting the lead into the mA connection and change the setting to read the current on the multimeter, it reads 0.
When I change the lead connection from mA to A, the power source circuit breaker breaks.

V=IR
The Attempt at a Solution
So then I tried connecting the ammeter in series with a resistor it started showing some current.
I later set up the new circuit with a rheostat, as shown in the second picture (with a diode and resistor in series with each other and another resistor parallel to it), and I tried changing the resistance using the rheostat, the current wouldn't change. Whether the diode was forward or reverse biased, it didn't seem to make a difference.
(I really hope that makes sense)
Thank you
