@Mary Yugo ,
I have already demonstrated that 25 to 30 mV DC across a 1 ohm resistor is possible while passing 1.75 A through it. The AC voltage across the 1 ohm resistor at that time was about 1.3 V true RMS. And there was 25 to 30 V true RMS across the whole circuit at that time.
The handheld voltmeter, when set to DV volts, won't give any indication of AC volts.
The Klein (orange) meter imaged in the Gullstrom-Rossi report reports DV volts, but not by default. It defaults to AC volts, and so must be changed to DC manually.
The 1 ohm resistor rated wattage sets the current limit to some degree. They can pass a fair bit of current, but they will get hot. How hot can be used to estimate the current. A 10 W ceramic resistor will reach about 70 C at a 3 W load.
