But if you add a resistor it will change the circuit subtly and it may have ... out that there are different probes for different current measurement regimes. High current, medium current, and ...

IsoVu isolated current probes from Tektronix isolate oscilloscopes from circuits used for EVs, motors, and power converters.

You need to know how to measure the current that flows through a component in a circuit and the voltage across it. The ammeter must be connected in series with the component – remember ...
