Which current types can be measured with a Shunt?
&quot;Typically&quot; is tough to pin down.  All 3 can be measured with a shunt, I'd say DC and impulses are more common than AC, which can be measured by a current transformer or Rogowski coil.
A current sense resistor is often used in series with the source of a FET in peak current mode SMPS control, one type of very common impulse application.
Open and closed-loop Hall effect transducers are fairly common too, so what's &quot;typical&quot; kind of varies with the application.
