The humble current shunt is an excellent way to do just that. Ohm’s Law. To understand current, it’s important to understand Ohm’s Law, which defines the relationship between 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.

Though there are ways to sense current without such intervention, the shunt technique nonetheless has many virtues. However, it also places unique demands and stresses on the active circuitry that ...

The resistors help with accurate current sensing in applications like electric vehicles, power tools, HVAC controls, and ...
