Like Chris, i am getting tired of explaining, in this case what reactance does with a csr.

I have no problems with the "measurement protocol" used overthere itself, they seem sound.

Chris is right about using a good csr in a DC environment.

There, a 0.1 Ohm (100 mOhm) 1% csr is very accurate in measuring DC currents.

But he conveniently does not mention what it does when dealing with AC signals.

The captainLoz device runs at 830KHz, so surely no DC.

Lets see what this means for a high quality Johanson 100 mOhm 1% 5W csr like the RMCJ3U000R1FS from Mouser recommended by Chris:

https://nl.mouser.com/ProductDetail/Johanson-Dielectrics/RMCJ3U000R1FS/?qs=ofF%252BRbqKDcYsoVgaSsLAJA%3D%3DThe specs (

https://nl.mouser.com/datasheet/2/611/rmc-series-1074317.pdf ) say:

• Resistances from 0.005 to 0.100 Ohms

•

**Low Inductance (<10nH)**• Tolerances to ± 1%

• Resistance Wire TCR: ± 20ppm/ºC

• For Current Sensing and Shunt Applications

• All Welded Construction

• Economical Bare Metal Element

So inductance = <10nH, lets say 9nH (it won't be much less)

According to this inductive reactance calculator:

https://www.66pacific.com/calculators/inductive-reactance-calculator.aspx9nH @ 830KHz = 0.05 Ohm = 50 mOhm

So at 830KHz (working frequency of CaptainLoz his device), the ADDED reactance of this csr is 50 mOhm, so the total resistance (Impedance) is 150 mOhm, which is an

**50% increase**.

If i would use a 1 Ohm (1000 mOhm) 1% csr, this same 50 mOhm reactance would only increase the total impedance by 5%.

But... even more important then this 50% increase in impedance of the 0.1 Ohm csr @ 830KHz is how it is measured.

When using a pcb with connections and a voltage probe like the Captain does, the reactance (and resistance) at 830KHz causes an even worse situation (900% worse) like shown earlier in this thread where i used my VNA to characterize that situation:
