I'm checking a Mini Fridge AC Compressor power consumption
Amps = Watts / Voltage
Example - 34Watts, 110v, AC
AC Amps = 34Watts / 110v = .31
BUT.....
Kill-A-Watt is showing AC - 34 Watts and .61 Amps ? (Power formula say it should be 0.31 amps.)
That's nearly twice the expected result. PF (Power Factor) ?
Then again, Kill-A-Watt is known to be very inaccurate at low power
How do YOU get your "accurate" results when checking things like this? Clamp on Meter?
Cheers
