A current flows through a resistor ... the current that can pass through the circuit, and also waste power as heat. For these reasons, the current shunt resistance should be as low as possible.

But even still, when following the circuits to their ends ... generation Insight involves a shunt resistor, which lets the computer sense the amount of current being drawn from the hybrid battery ...

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 ...
