RE: DC voltage drop across choke vs resistor!!!

Hi Tre

I am not explaining this correctly. The circuit is biased with a diode. This is why I do not check the voltage drop there. So I would normally would check the voltage drop across a choke with known resistance and do the math from there. A buddy told me the choke measurement is not as accurate as a series resistor. So I put a resistor in series and then measured across the resistor and the choke. After the math it was 16 ma for the resistor and 18 ma for the choke.

So everything is constant the diode is setting the bias for the tube the b+ is settled in to what ever the current is. So all I was doing was checking what the measured current is.

So my question is why would the drop across the choke DC resistance measure different than a standard resistor?

Thanks Tom
