A rising tide of speculators are arguing that Nvidia's 16-pin 12VHPWR standard is designed with no safety factor, causing ...

This is the underlying principle behind the current shunt. A current flows through a resistor, and the voltage drop across the resistor is measured. If the resistance also is known, the current ...

There’s many different ways of measuring current. If it’s DC, the easiest way is to use a shunt resistor and measure the voltage across it, and for AC you could use a current transformer.
