Are you sure the 1.65 +/- 5 mA is correct? That could be any value between 6.65 mA and -3.35 mA.
Did you mean 1.65 A +/- 5 mA ?
The rheostat in the circuit allows the current in the resistor to vary with a fixed-voltage power source (like a battery).
The problem says 1.65 (plus on top and the minus sign below it) 5 mA
I think the plus and minus is the uncertainties.
How would you be going about it doing both values....
I have no idea how to solve it and what the outcome is?
