The relatively simple modification to the first-generation Insight involves a shunt resistor, which lets the computer sense the amount of current being drawn from the hybrid battery and delivered ...

However, often these circuits draw relatively small currents that are ... The probe consists of a low value resistor of just 0.1 Ω, acting as a current shunt in series with the desired load.

shunt resistors are used to measure the current flowing through a circuit. Ideally, each of the six 12V pins should have its own shunt resistor. With the RTX 30 series, Nvidia included three shunt ...
