Hello,
I am required to measure current which can be up to 10 Amps.
Which is the most accurate of the following three methods?….
…one is a non-inverting amplifier, and the other is a differential amplifier.
Non inverting amplifier (Gain 101)

Differential amplifier (inverting) (Gain 100)

Differential amplifier (non-inverting) (Gain 100)

The opamps feed into microcontroller ADC inputs
Here are the schematics in pdf
