Component: R4 (3 kOhms)
Component: Op-Amp
The Op-amp should be able to output voltages up to 5V. A single-supply op-amp is being used as this will be able to output voltages close to the supply rail (0V to 5V) (rail-to-rail output op-amp).
Input voltage range must allow op-amp to handle small input voltages that the shunt resistor will be providing.
